It is a manual machine. The 1J head has 4 speeds adjustable by belt setting and a backgear drive for 4 more speeds, as you show. Probably has the R-8 spindle taper. 1 Hp motor, 3 phase.
But, that's just the specs. Condition is everything. Ways can be worn, Acme screws can be in bad shape. If you want to convert to CNC, then starting with a machine already set up for CNC is a much better choice. If you want a manual machine, then that doesn't matter.
