Antique Geo. P. Pilling Medical Dental Compressor Bipolar Ajax DC Electric Motor

Description

Very interesting and early use of an electric motor for a medical or dental devise. The motor has a cast brass tag marked Ajax. It turns freely. The pully fits on the nickel plated pulley and turns easily. The piston goes up and down and is clean inside. I looked, the cap unscrews. Check out the various speed switch and area underneath. I am not going to try anything and am selling it for displaying. This is a super piece.
