I don't know enough about lathes to evaluate it's condition.
This tells me you don't want to buy that. How much wear it has dictates if it would be worth rebuilding.
In it day it was probably a good well featured lathe, that was a long time ago. I would say 40's or so.
It has a taper attachment, norton type threading gearbox, clutch drive with a geared head, which is good, whats bad is the threaded spindle nose, which means no reverse running, missing carriage handle, which you could replace with out too much difficulty and the terrible condition.
Its a make that is uncommon (first one I have seen) so most likely you won't find parts for it if you need them, even used.
I wouldn't huy it even for scrap price but I have no desire to rebuild old lathes
