I have a copy of the Ragtime "O" roll tracker bar schematic.  It
shows the hookup of all functions, from "Play" at far left to "Crash
Cymbal" at note 88.  I received the schematic along with other service 
information when I bought my 1911 Lester upright which had been modified
with a Ragtime kit in the 1970s(?) in Baltimore.  Recently, when the
fallboard got jammed, disassembly revealed the culprit: a ball point pen
from a Baltimore towing company!

I have let Bill Maguire know about this diagram if he is interested,
and I'm ready to copy anything else that anyone might find useful in
servicing a Ragtime Automatic Music orchestrion.  Meanwhile, I am ready
to accept any hints, etc, from others who have any wisdom about
repairing my five non-working pneumatics on my Ragtime nickelodeon.

Thanks,

Tom Sendall
