I have seen this in person, it is located at the New England Air Museum at Bradley airport in CT. This motor is so sweet, it is completely logical in every way. If no one had ever showed me how engines are made, this is probably what i would have built! Funny, it's for their aircraft but it has tons of bronze and brass parts. I guess it was what they had available and it's really easy to work with. How sweet would this look in a bike?
