Contrary to all of the guessing, This is an old long stroke air compressor. The previous picture is a very old industrial, electric motor. it powered the old fella.
The large fly wheel turned slowly at around 180 rpms. We still support parts for these old dogs that are in the bottom of mining operations and are too costly to dismantle, remove and bring down a new one in parts and put together. This model was produced from 1905-1950's
