I have a Baldor grinder likely the same model era, the one pictured could be a 1/3 to 3/4 hp; power cord looks awfully thin for anything but 1/3hp. You need to ask for more info. For your info, at minium you should get is 1/2hp, with tool rests. If purchased motor will need internal cleaning, bearing cleaned and greased ( open bearings), and possible new run capacitor, likely new wheels; that said, in the era of manufacture these motors produced true rated horse power not "wannabe" hp. Very heavy for a grinder if shipped
