Rare Gasoline Powered Saw

Having spent an hour on the internet I cannot find any information on this portable gasoline powered saw. It has to be one of the earliest portable self powered saws made, one cylinder engine, belt drive (the original was probably leather), steel wheels, wooden chassis with two handles for maneuvering it, a sliding cutting table, safety guard over the blade (which did not give much protection to the operator!) Just was just something that made me stop and marvel at the tools that built America, it is truly a part of American history.
