[GreenKeys] Seeking model 15 platen crank

[ken Schwieker]

I ordered several cranks from Fair Radio to see if a sleeve can be 
constructed to adapt a KL crank to a model 15. Courtesy of Joe 
Clanin's excellent photos
it appears there is a sufficient size difference between the inside 
dimension of the Kl crank socket and the inside of the 15's crank 
socket for a sleeve.
Time and some work will tell if this project is successful. If so 
they will be available at cost. I have both a 15 with crank and a Kl 
with crank to work with.
