Leroi portable compressor

[Diesel Doc]

I have a 1969 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 un-loader valve, the diaphragm. So far I have not been able to locate a dealer that might have Leroi parts. If anyone might have an idea as to a source of parts, please let me know. Thanks!

Thanks John, I sent them an email along with several other companies I found on the net. No response as of yet. Apparently LeRoi doesn't have a loyal following like Cub Cadet!
