Here's a rare piece from my collection. It is a 6 cylinder radial engine. Made by Ingersoll Rand. Its a Spot Air 3-R-36 portable air compressor. I even have the very rare hand cart to move it around. 3 of the cylinders operate the gas engine and the other 3 are for the air compressor. These were made for the railroads in the 1940s and 1950s.
