Nice old machine with new motor.....is that an actual Baldor motor? Really nice!
Hard to tell the condition of the lathe ways to give a value estimate.
Nice to see the original cabinet and legs.
Some people will put it down due to lack of Quick-Change Gear Box (QCGB), meaning that you need to manually re-arrange gears to select feeds.
If you do decide to sell then "extras" like chucks, gears, steady rest will add value.
Me? I would lube it and test it.
Start playing with it and I bet you could find some uses for it.
