All is made clear with re-building this vernier shaft assembly in my Service Tip #39.
It does show the 1938 version, but I believe they are the same assy. or very close
so you can use the info and diagram.

Hi Chuck - thanks for the reply.  I did see the Service Tip previously.  Looking at the assembly shown in in the Service Tip, I don't understand how the fine tuning shaft stays in place.  I used the diagram to assemble the parts, but it doesn't yield a working fine tuning control.  Desperate and looking to satisfy my own curiosity, I super-glued the small ball bearing to the end of the fine tuning shaft.  When I assembled as such, it seemed to work and the fine tuning shaft was held in place nicely.  Within minutes, the super glue failed and left me where I started.  I know... the experiment sounds like heresy.  I removed all traces of the glue and I'm back to square one... clueless.
