South Bend - To Be Done

As I've tackled the South Bend 22YB "Junior" lathe, I've found a few things wrong.  Inside the spindle bushings, I found some small grooves in the spindle :

Also, the handle had broken off on the back gear, as well as a missing tooth on the "bull" back gear.  I'll try to braze fill a "tooth", and I picked up a handle for a "workshop" 9 back gear.  The handle doesn't fit (hole too big), but if I'm brazing it, I might as well fill the hole in that handle and use it anyway.  That's my next focus.

Plus, I need to identify a clamp - I'm not sure where this one goes :

We'll see what happens!
