This entry describes an original installation of a new pipe organ.
Identified by Scot Huntington, based on personal knowledge of the organ.
-- This, the first Holtkamp installed at the College, represents a "Martini" model practice organ, built on the unit principal and installed in a practice room in the original Music Department building. This same job number has also been assigned to the large concert auditorium instrument installed after Walter Holtkamp Sr.'s death in 1962. Ferguson in his book on Walter Holtkamp, assigns job number 1666 to this 1953 instrument, and the numbered listing in the book ends with Holtkamp's death in 1961. My unofficial listing of Holtkamp organ's assigns job number 1747 to the 1962 auditorium instrument. Prof. Charles Finney, organ professor and chair of the Music Department and who was in charge of the purchase of both Holtkamp instruments, told me that there was an option of pedal stops available for the Martini-style practice organ. The basic design came with a 12-note wood extension of the wood Copula 8' (the bottom 12-notes of this rank also serving as a bass for the Quintadena 8'), but the more costly 8'/16' metal extension of the Quintadena was available as a cost-plus option in lieu of the wooden Pedal Bourdon, and that option was selected for this instrument.
