Dear John, Greetings from The Bronx (which at one time was the central
hub for the manufacture of player pianos). My recommendation to you is
to consult the Pierce Piano Atlas, which is in it's 12th printing.
Rather than purchasing your own copy, your best bet is to go to a local
piano store (that is, if any still exist; the last one in The Bronx
closed in 1985). Your piano tuner might even have a copy of the book.
Are you certain of the name of the piano manufacturer? Check the name
on the fallboard (keycover), then compare it to the name on the piano
harp, which is usually located on the upper right corner. Go with the
name on the piano harp, along with the serial number to research the
age of your piano.
Hope this helps,
Dale F. Rowe
