I found these on cl and was wondering if anybody has heard of the brand lima and put a name to the grinder with the buffer wheels asking price is $150 for both
The top grinder appears to be a U.S. Electrical Tool Model 500. A top-line machine. Unfortunately it's missing it's cast-iron guards, which weigh about 100 lbs.
The bottom grinder is a Lima, made by Lima Electric in Lima, OH. As far as quality, like most true industrial grinders it makes a Baldor seem like a cheap toy.
