Dear Brian, Greetings from The Bronx,  In regards to your inquiry,
if my memory serves me correctly, the orchestrion components were
manufactured by a company by the name of "Ragola".  I purchased
several components from them when they first offered them.  I had
intended to build my own 'O' roll machine but wound up using some
of the components in a customer's piano instead.

Hope this is of some help,

D.F. Rowe
