That is very nice, Arnold. Yes, it looks like a smaller version of the engine I recently acquired, redstored, and posted about. Yours is certainly in excellent condition. I think that the number may be in the 2166 series. See Schiffmann, Band 22, p. 188.
Can you post or send me a close up photo of the face of the manometer? Thanks in advance. Jim
I will post a picture tomorrow. The Schiffmann has no measurements and very few info for the 2166 - also the values that are declared are a joke - nobody would ever sell such a rare engine under 500 - my opinion. It is a heavy and quality engine and can not be compared with Bing/Doll smaller engines.
