I'd start by looking at it really close... look at the end plates, crankcase, oil filler and sight glass, cylinder shape, cylinder head, and valve boxes, then through photos of antique air compressors. Speedaire, Brunner, Quincy, Champion... evenutally you'll see a cylinder head that looks like yours, then search deeper.

Compressor manufacturers tended to use cylinder and head designs that were modular... a single cylinder compressor could be made into a multi by casting a new case, forging a new crank... or a two-stage by making a different crank and rod for shorter stroke on the HP stage... or smaller bore on the HP stage... but they looked the same. Once you've narrowed it down, details will typically tell you the rest.

That's not like any compressor I have ever seen before, and I have seen quite a few although most I have paid attention to were much older than that one. Several makers had dual stage V twins including Westinghouse and Worthington but again those were much older than yours and if memory serves all of those had disc valves except the I-R type 30 which looked nothing like yours.

Once they got to that size most companies that made vee type compressors had four cylinder models, for the reason alluded to by Dkamp, the ability to recycle smaller cylinders pistons heads etc.

Are the fasteners on that thing metric or conventional? It may be an import. Although going by the date on the tank some US manufacturers might have made the change by then.

Looks similar to an Ingersol-Rand my fire department has for the alarm horns. Ours dates back to the 1940s

thank you to all that have posted. Figure i would find the one that no one has a definite clue where it came from, love a good challenge. thankfully it runs perfect and makes air very quickly. would like to up grade motor, it looks like mice used it for a home at some time , i replaced a lot of the chewed up wires. so many projects and so little time .

Yup, I thought that thing had a furrin look about it. But my first guess would have been Italian or maybe Spanish. And yet it is... Brazilian! Interesting. Thanks for posting what you found. It's always good to have a puzzle solved.
