The compressor is single-cylinder, air-cooled. There is nothing on it to identify the manufacturer. It looks like the S.C 4 compressor covered in the manual. The manual doesn't say who made it either, so it may be Perkins' own manufacture.
I think I have most of it figured out. I went back for another look at the engine it came off, and there's a tapped hole in the oil gallery within reach of the piece of tubing that came with the compressor, so that must be where the oil feed comes from. No sign of any restrictor other than the small-bore tubing. It looks pretty obvious that the oil drains back into the engine through a passage in the base of the compressor.
Re-reading the manual (why didn't I do that before asking?), it does have some information on the air plumbing. I guess I missed it the first time because there was no diagram. It says that "the compressor draws air from the engine induction system", so no separate air cleaner. It also says "the compressor unloader mechanism is built into the compressor and is operated by reservoir pressure fed back to the compressor governor through a small-bore pipe", so the only other small- bore pipe on the compressor has to be the pressure feed-back. I didn't get the reservoir with the compressor, but it shouldn't be too hard to improvise the connections to the reservoir I do have.

The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
