Can someone tell me the size of the left hand supply fitting
on a Standard Action.  Did the size change through the years?
I have a customer who has a defective supply roll chuck on the
left end of the spoolbox.  This is the one you push in with the
roll when putting it on the piano.

If someone has a spare in their stuff, please drop me a note
with your asking price.  Really hoping...!
