Looking for info on the maker…unknown at present. We believe this to be either an early auto or aero engine. Made around 1905 based on use of 1/2-12 fasteners. This is a three-port, two cycle engine where the piston skirt valves the charge going into the crankcase. The flywheel end of the crankshaft has a tapered section for the flywheel to mount. The flywheel is probably not correct as we have no clue what was originally on it or if it was a propeller as used on an airship or aero plane . May also be an early auto engine as evidenced by the mounts. Use of so much aluminum in the crankcase is unique for that time period.
