help identify compressor

[bwanacandu]

New be needs some help identifying this old compressor. I have a cylinder with no mfg tag. The only markings are as follows- below the shafts is "BP", to the left is a reversed " R" abd a "P". To the right is "2", and below evertything is "OL". It has a knock after a few minutes running and an air leak at one of the low side valve cover. I really would like for it to have a few more years of service if i can find parts . Any assistance would be greatly appreciated

It's a champion pump. I believe Grainger also sold them under the speedaire name

I may have a few parts that will work on this pump.

Great, I haven't pulled it apart yet. I'll let you know what I find
