Randy Stanley said [in 140814 MMDigest]:  "I am in the process of
building a "John Smith" 20-note busker organ from plans purchased from
Ken Schweim on eBay and I need to get a test roll along with several
song rolls.  Does anyone have these items available?  ..."

Mel Wright is the right guy to contact.  See his music sales site for
(1) music rolls for the John Smith organ, and (2) hints on building
crank organs, particularly from the John Smith plans.

There is a section devoted to the John Smith Busker.
