In tracking down the cause of a sluggish rewind pneumatic, it was
not possible to see the control valve.  The piano is a late model
Chickering B, and plays unusually well, until it is asked to rewind!

In spite  of an older, first-class rebuild, the belly cloth is cracking
and splitting.  Some access panels are wood, unlike most Ampico A's
I've seen.  So instead of removing panels, I delayed further investi-
gation until I can locate the faulty valve.  If anyone can guide me to
a book or diagram I'd be most appreciative.

 [ Bill, the rewind valves of the Ampico B are located inside the left
 [ side compartment of the drawer.  At the MMD tech data site are some
 [ drawings from the Ampico B 1929 service manual which might help you:
