The Green one is a Winona Van Norman. I bought that machine in 1987. Used it at the Parts Store to turn rotors and drums for customers. Very Heavy Duty. Could turn truck drums with the dual wheels still attached to the drum. Paid 10K for it new. When I sold my stores, Carquest put it out on the dock and didn't want it anymore. I bought it from them for $500..LOL Took it to my buddy's shop since he had more room.
