Working with Matthew Caulfield on ephemera dated after 1970,
I have put together a large spreadsheet database of a portion of
the Wurlitzer Automatic Player Piano (APP) and Caliola music roll
This database, which will be shared with the MMD when completed,
documents the music rolls sold by Doyle Lane, Player Piano Company
of Wichita, Play-Rite and Ray Siou.
With the acquisition of a large collection of Caliola rolls from the
estate of the late Tom Grace, I acquired the loan of a 1920s Wurlitzer
catalog, which I copied to PDF files and returned the original to the
What I am now seeking is photocopies or scanned image files of APP or
Caliola catalog ephemera relating to Wurlitzer APP rolls produced in
the 1930s. This will fill in the gaps of the roll database up to when
T.R.T. took over roll production.
