[GreenKeys] Wanted: Teletype P/N 72563, Washer, Felt, for Model 15 main shaft

[John Nagle]

     I'm restoring a Model 15, and it looks like the felt washer 72563 on
the main shaft is shot. The selector clutch is slipping.  I can 
hand-crank the machine through a cycle and see the cams stop moving for 
a moment.

     The selector problem seems to be not stuck swords, but a slipping 
selector clutch.  I can hand-crank the machine through a cycle and
see the cams stop moving for a moment.

     The felt washer 72563 doesn't look too good. See:

That's probably what's slipping.

Anyone want to sell me one, or swap for some other Model 15 parts?
I have a Model 15 repair kit, with most of the smaller parts,
but not this particular felt washer.  thanks.
