Thanks, everybody, for all your help [081202 MMDigest].  Debbie Legg
was the first to respond; she emailed me a nice tubing diagram that
she drew up for a later model Ampico upright showing how the repeat
and shutoff system works.  I offered a $50 reward for information
leading to the figuring out of this setup and she said to donate it
to MMD, so I will do that.  Thanks again everyone.  Happy holidays!
