Found this at an estate sale. From what I can tell, the compressor is powered by a Briggs and Stratton Model I, which puts the manufacturing date in the 1940s. Compressor only has a couple markings (X2-4 on front, 2100 on top).
Engine seems OK, just needs carb rebuild and tank cleaning. Did start with starter fluid.
Any help on identifying make, model. Don't want to do too much to it but would like to update the paint to the original color.
