When I tried to tighten the ladder chain sprocket for the transmission
in a 1912 Kimball, the shank where the set screw is attached broke.
This sprocket is a 13-tooth, with a bore diameter of what looks to be
1/4 inch, or it could be 15/64".

I need a replacement.  I've looked at Stock Drive Products and Zoro
but I'm not seeing anything that looks exactly like it.

 [ The steel sprocket disc seems okay.  Ask a machinist to make
 [ a new hub and press the old sprocket disc onto it.
