In reply to requests about roll frames for a Wurlitzer 125, plans
for making a Coinola frame can be found in the Vestal Press Technical
Series, now handled by Player Piano Co., 704 E. Douglas, Wichita, KS
67202.  You will have to send snail-mail as they don't go for Internet.
This would do for a 125 with a different tracker bar.

Frames are available from Gordon Forcier <Organgrinder48@aol.com>
He might be able to supply a 125 roll frame tracker bar, although he
has trouble getting the brass stock from time to time.

Gordon can supply many items for band organs and you will find him very
glad to help you with any problems.  He was the first person to build
a band organ from my book (1985) which is now available as a PDF if
anyone is still interested.
