Thanks to all who posted in the thread. When I was researching Bohaboy engines, I discovered that Dave (Firefite) has castings, casting molds, and some of these Bohaboy engines. Anyone heard from him recently; I hope he is OK, he was last active in April on the other forum?
The two cylinders marine engine is very similar to Boucher that makes me believe some of the collectors saying A. Bohaboy made some of Boucher models. The Bohaboy model has BW 100 engraved on the oil bassin casting.
