Documenting Skinner Originality When the Console or Mechanism Has Changed

A nameplate can be taken off a console and another put in its place, so the plate now present may not be the plate the builder fitted. The Diapason’s 2022 study of the G. Donald Harrison signature organs records one instrument where the original Aeolian-Skinner company nameplate and the signature plate were both stolen and the console now carries replacements. The same study repeats an account of an employee of the console engraving department making keychain fobs out of Harrison signature plates. These are documented cases from one builder lineage; they show that a plate is a fitting rather than an inherent property of the instrument, not that plates are usually wrong.

Replacement plates have been made with relative ease where originals were lost, stolen or broken, and the study’s author, Neal Campbell, cautions that ‘It is not difficult to fabricate these signature plates.’ A replica made in good faith to replace a stolen original and an unauthorized reproduction look the same on a keyslip. That is why the presence of a signature plate is not by itself proof that the instrument is one Harrison signed, and why a plate is weighed against the opus lists and the archival record rather than relied on alone.

A Skinner nameplate does not establish where an instrument was built. Jonathan Ambrosino, in his essay ‘A History of the Skinner Company’, records that the organs produced at the Skinner Organ Company’s Westfield Branch, the former Steere & Son works acquired in 1921, were at first merely Steere organs with Skinner nameplates, and that Dorchester factory construction details were assimilated into Westfield practice only gradually, so that by 1929 the distinguishing characteristics of a Westfield organ were few. Ambrosino makes the point as a historian of the company rather than from footnoted records, and it is bounded to one branch in the early 1920s; it does not make Westfield organs suspect, but it does mean that a plate from that period says nothing on its own about which factory the instrument came from.

A plate can also carry a later firm’s name onto an earlier instrument. The organ at Stoneleigh, Villanova, Pennsylvania, as The Diapason described it in December 2018, began as the Aeolian Company’s Opus 1790, was assigned the Skinner opus number 878, and carries an Aeolian-Skinner nameplate. How often replating of this kind happened is not documented; the case shows that the firm named on the plate and the firm that began the instrument can differ. Which firm was trading on a given date, and what an opus number means, are questions for Skinner and Aeolian-Skinner Identity, Company Eras, and Opus Numbers.

The company nameplate carries the firm’s name and not the opus number; on the Aeolian-Skinner instruments that have one, the opus number and the date appear on the separate G. Donald Harrison signature plate, which is additional to the company nameplate rather than a replacement for it. For the firms before 1932, the Aeolian-Skinner Archives website publishes photographs of two differently worded plates, a ‘Skinner’ nameplate from Opus 511 at Murfreesboro, Tennessee, contributed by Pat Parris, and an ‘Ernest M. Skinner’ nameplate contributed by William Van Pelt. The acknowledgement establishes that the builder family used differently worded plates; it gives no transcription of either, and as of September 1, 2026 the photographs themselves were not on those pages. So the wording of a company nameplate can bear on which firm an instrument belongs with, but the published reference material for reading it is thin, and the era question itself belongs to the identity page.

The G. Donald Harrison signature plate is an additional ivory plate, fitted after the Second World War to some Aeolian-Skinner instruments, bearing a facsimile of the signature of Harrison, the company’s president and tonal director, together with the opus number and the date. The Diapason’s study reports that the practice began in 1948 with the Salt Lake Tabernacle organ, Opus 1075, at the request of the organist Alexander Schreiner, Harrison having expressed the wish ‘I would like to have my name in the form of my signature if I can get this engraved in Boston.’ The archived opus list gives Opus 1075 a contract year of 1947; the two years describe different events and are not to be run together. Harrison died in 1956, which bounds the practice.

Because the plate names an opus and a date, it can be checked against the opus lists in a way a company nameplate cannot, and named instruments reported to carry one include Opus 1149 at New York Avenue Presbyterian Church, Washington, DC, 1948; Opus 1173 at First Presbyterian Church, Kilgore, Texas, 1949; and Opus 1174 at First Baptist Church, Longview, Texas, 1951. The years are the article’s own, and the article does not say whether they are contract, installation or plate dates. One further caution travels with the plate: an opus number on it is not proof that the console or the pipes are Aeolian-Skinner work. Opus 1208 was a rebuild of a 1943 Hillgreen, Lane & Co. organ in which Aeolian-Skinner reused most of the pipes and the console, and that console retains its Harrison signature plate.

On the post-1945 signature organs the study discusses, the company nameplate sits on the left of the console nameboard, or keyslip, and the signature plate on the right, an arrangement the article describes as ‘a signature plate on the right of the nameboard [keyslip], complementing the company plate on the left’. That placement is documented on the Tabernacle organ in Salt Lake City, on one named instrument, which is not the same as a company-wide rule.

A console can also carry more than the two plates. Opus 1200 at the New England Conservatory carried the company nameplate, the signature plate, and a third plate recording the instrument’s use at a convention, and at the Cathedral of All Saints, Albany, Opus 1275 carries one signature plate indicating that Harrison was responsible for the Great and Positiv divisions and another indicating that Whiteford finished the Swell and Choir. Each plate is read for what it says, since a plate commemorating an event or dividing tonal credit is not a builder’s plate, and each of these is one documented instrument.

No documentation explains which Aeolian-Skinner instruments received a signature plate or why. Campbell writes that ‘There is no definitive information to suggest why some organs received this signature plate, what criteria were used in selecting them, or what purpose it served.’ Philip Steinhaus stated in 1968 that Harrison agreed to signature plates only ‘on the jobs with whose finishing he was deeply and personally involved,’ and that account stands as one practitioner’s recollection rather than as the operative rule, since the same study says no definitive criteria are known. Campbell identifies about twenty-five signature organs built between 1948 and 1956, calls the list complete and accurate so far as he knows, and expressly expects there are others he does not know of.

Three consequences follow. A plate’s presence is not a quality or authorship test. Its absence says nothing against an instrument, because the practice covered some jobs rather than all, and an opus number on a console plate is the exception rather than the rule for this builder family. And an instrument missing from the published list is not thereby shown to lack a plate.

No published statement locates the company nameplate on the pre-1945 instruments. The Aeolian-Skinner Archives website’s acknowledgement of the Opus 511 and Ernest M. Skinner nameplate photographs does not say where on the instrument either plate is fixed, and the Opus 511 specification page, as it stood on September 1, 2026, carries three images with no caption locating a plate. Those pages are silent on the point at that date, which is not evidence that the plates lacked a standard position. The documented keyslip placement covers the post-1945 signature organs only.

A marking position is builder-specific, era-specific and instrument-specific: the same kind of search that finds a keyslip placement for the post-war Aeolian-Skinner signature organs and a photographed console nameplate on an 1869 E. & G. G. Hook instrument finds, for the Reuter Organ Company across its 1917-2022 output, no source stating where a plate or opus number was placed at all. No single instruction covers even these families, which is why this page describes evidence classes and not a checklist.

Hardware of more than one vintage inside a single console shell is an expected finding, not an anomaly. Console rebuilding, as rebuild services describe it, replaces stop controls, pistons, shoe contacts and the combination action while retaining the shell, keyboards and pedalboard, so the age of a shell is not evidence for the age of the controls inside it, and dating those controls needs documentary evidence such as builder records, plates and service records rather than appearance. That is a limit on inference rather than a dating method: it rules out one way of dating a console and does not supply another.

The documented cases show what the mixture looks like. Wicks records that the original console of Aeolian-Skinner Opus 1083 had ebony drawknob stems with ivory faces, engraved ivory tags, ivory coupler tilt-tab faces and ivory pistons, and that the console presented, besides playability problems attributed to age and continued use, unsightly holes left by past alterations, so that damage inherited from earlier interventions is itself a condition to record. Létourneau reported that Aeolian-Skinner Opus 1257 of 1955 had original silver-wire and bronze-plate key contacts and original pneumatic stopknob actions, and that in the restoration the contacts were renewed with new silver wire while the pneumatic stopknob actions were replaced with electro-repulsion solenoids. After work of that kind the shell, the keyboards and the plates are older than the actions behind the knobs, and a record of which is which is part of what documenting originality means. What those actions are and how the generations differ is explained at Skinner Console, Relay, Combination Action, and Later Retrofits.

A console can be another firm’s work entirely, playing pipework attributed to this builder family. At First Congregational Church of Los Angeles, the church’s own record states that the Trustees ‘awarded a contract for the construction of two mammoth five-manual consoles to M.P. Moller, Inc.’, that the Chancel console ‘was installed in November, 1992, and was the last masterpiece designed by the venerable Moller firm’, and that the twin Gallery console ‘was completed by former Moller craftsmen at the Hagerstown Organ Company’, while the pipework it lists is by Ernest M. Skinner (1931), the Herman Schlicker Organ Company (1969) and others. The instrument’s attribution and its console’s attribution are separate statements, each with its own maker and date, and a composite instrument of this kind is described accurately only by keeping them separate. Opus 1208, noted above, is the converse case: an Aeolian-Skinner opus number on a console and pipes the company reused from another builder’s organ.

Opus numbers were stamped on pipework as well as fitted to consoles, and a stamp on a rank records which contract that rank was made for, which is not always the instrument it now stands in. The parish record for Opus 769 at All Hallows Church, Wyncote, Pennsylvania, a 1929 instrument it lists under the ‘E. M. Skinner Organ Company’, states that the job was rushed after a January 1929 fire for completion by Christmas Eve 1929 and that the organ contains pipework from four other opus numbers in the Skinner series besides its own. The same record notes that the lowest twelve Dulciana pipes substituted into the organ are stamped as the Aeolian Company’s Opus 784, although they were built by Farrand and Votey in 1896.

One instrument thus shows three things at once: that opus numbers can appear on pipes and not only on a plate, that a stamped number identifies a contract rather than the present instrument, and that an Aeolian Company number of the 1890s can sit on pipes physically made by a contracting firm. Reading a stamped number as the instrument’s identity is a specific and documented error. This is a single documented example and does not describe universal practice at either firm.

Components moved between instruments carry their origin with them, and a documented restoration can bring parts of several named organs under one opus. The Diapason’s account of the restoration of the Skinner Organ Company’s Opus 708 for the Parish of All Saints, Ashmont, records that the instrument as installed incorporates a horizontal trumpet from the parish’s prior chancel organ on a Skinner Organ Company windchest, reservoir and pipes, electro-pneumatic switching taken from the 1928 Princeton Chapel organ, and control knobs taken from the 1926 Skinner Organ Company console at Trinity Church, Boston, with the remark ‘The engraving doesn’t match; we don’t mind.’ Mismatched engraving on the knobs is, in that case, the visible trace of a documented import. The record of what came from where is what makes any statement about such an instrument’s originality defensible.

Dates written inside an instrument can corroborate a published opus list independently, because they can be compared with the alteration dates the list records. One documented case rests on a photograph of an inscribed wooden Pedal Bourdon pipe held in the OHS Pipe Organ Database image store, read against a database note reporting the published list; the match there is between a provisional reading of partially legible handwriting and a secondary note, with neither pipe nor list examined physically. That is the strength and the weakness of the class at once: an inscription is primary evidence made at the time, and in the documented case it was partial and hard to read, so it corroborates rather than decides.

A factory stoplist describes the organ as it left the works, not the organ that stands in the building now. The archived opus lists on the Aeolian-Skinner Archives website state that their stoplists show the organs as they were when they left the factory and that the lists are meant only to supplement, not replace, the published opus list; the website directs readers to the printed Kinzey and Lawn opus list for notes on current condition and alterations. Read that way, a divergence between the archived stoplist and the instrument is evidence that the instrument was altered after it left the factory, not evidence that the list is wrong, and the list cannot be relied on for the present specification. The printed volume is the named next step for alteration notes; what the contract files and engineering stop lists hold, where they are kept and how they are requested is the subject of Finding Skinner and Aeolian-Skinner Factory Records.

The owning institution’s file can be the fullest single account of an instrument’s changes. The Church of the Advent, Boston, keeps a public record for its 1936 Aeolian-Skinner Opus 940 that includes a dated narrative history prepared and later revised by named organ historians, a published technical specification sheet, a photograph gallery spanning decades, including historical photographs, and references to commercial recordings featuring the instrument. That is one congregation’s practice and not a template other owners are known to follow. It does show what such a file can hold, and the same components, a dated history, a specification and photographs, are what insurer- and practitioner-side sources describe as supporting a pipe-organ insurance valuation, so a record kept for the instrument’s history serves a second purpose it was not compiled for.

Two published accounts of the same instrument can differ in exactly the details that matter for attribution. For the Skinner Organ Company’s Opus 708 at Ashmont, the parish’s own page records the instrument’s date, size, provenance from a closed church in North Adams, its 2012 acquisition and its 2015 installation, and records none of the components imported from other named instruments that The Diapason’s restoration account describes. Neither account is wrong about what it covers; the owner’s account is a history of the instrument and the trade account is a record of the work. The difference means that a single account of an instrument, including the owner’s own, is not a complete statement of its originality, and that the divergence itself is worth recording with both sources named.

The evidence classes above are assembled rather than ranked: the plates as read, with the opus lists they were checked against; the interior markings, stamps and inscriptions, with what each was compared to; the console hardware by vintage, with the service records that date it; the factory stoplist as the factory state; and the owner’s file and any trade account, with the points where they differ. A file of that kind is what an inspection documents and what any proposal has to be measured against, and it is the body of evidence a treatment decision starts from. That decision, whether restoration or rebuilding is the right word and which state would be restored, is made on Restoring or Rebuilding an Altered Skinner Organ. Nothing on this page concludes what any particular instrument is.
