LeRoi Rotary Compressor 150RG1E
 

I have a late '60's tow behind portable air compressor made by Leroi which at that time was a division of Wabco (Westinghouse Air Brake). I'm looking for some parts for the compressor unloader valve, the cylinder diaphragm. So far I have not been able to locate a dealer that might have parts for this antique. If anyone might have an idea as to a source of parts, please let me know. Thanks!
Leroi model 150 RG1E serial# 287X317

I'm sure you have tried the net',
Sometimes the hokey ass message board (HAMB) guys talk old compressors, also the old construction machinery guys might be a try as well as smokstak.com
Is what you are seeking something that can be repaired or machined?:bigthink:
is it a mechanical unloader or air powered diaphragm unloader on the valves?

Compressor is a rotary vane type and the diaphragm is located in a pneumatic actuator for the door on the inlet to the vane chamber. Closing the door unloads the compressor.
