The one I am looking at has a 3 phase motor and I am seriously
considering just adding a VF Drive to it. Program it for say 3 fixed
speeds on the motor and using the lathes variable speed control. Does
that sound feasible? Or would it be better to just go full electronic
speed control and skip the reves drive?
Once I get it in the shop and torn apart that will really help me decide.

===============
All electronic is OK if you have enough horse power. Otherwise, the Reeves
drive can give you additional torque at low RPMs. If the low end is in the
500-700 RPM range now, you can go that low mechanically, then drop down to
200-300 RPM with the VFD and still not lose turning torque.

The part diagram would be great to have when I start to rebuild it!!
