Still cleaning out things from the last move, I found pictures of
a music roll perforator that was built before the days of electronics.
It is a one-to-one perforator designed to copy existing music rolls.
Details of operation are not available, however, note the maze of
rubber tubing, organ magnets and the ubiquitous Autotypist pump on the
floor under the motor platform.

With such a large flywheel, it must have taken a long time to punch
a roll, but I am told that it worked.  Several people I know have music
rolls made on this machine.  See the pictures here:
