I wonder whether anyone can help me with a problem I have been having
with a Welte Licensee pump?  After a lot of work, the pump is now
airtight, but the original straps from the crankshaft to the bellows
had been replaced at some time in the past.

I have replaced them with sections of neoprene/rubber belt with two
strands of canvas running through it.  But they seem to bend too much
when the pump is under tension with the result of loss of suction!

Is there any MMDer who can give me the specifications for the
connectors or, even better, can offer to send me enough material to cut
up and use.

As you might be aware, Welte Licensee pianos, uprights or grands, are
extremely rare; so it is not possible to just get in touch with another
owner in the UK.
