I am restoring this engine for an old friend of mine- is it a model or just a small engine?. In the process of having 2 flywheels cast (missing) from the pattern shown and making an eccentric to actuate the steam valve. Does anyone recognize the model? I am guessing he has had it for 30-40 years.... Would like to see how it should look. Lots of the parts were fabricated from bar stock like the crank journals and crosshead.
