My Pa has
a couple of Fairbanks-Morse 1 lungers ; as they were called. I don't remember if he ever got the larger one running. The smaller
one, iirc, is a 5hp. We used it to drive an eliptical weight gold mill at our claim in Sierra County Ca. I think it was in '66 - '67 , maybe
'68. Noisey , but plenty of power! I think F - M must have manufactured many turn of the century items. I remember seeing a real
fancy step on scale in a collectibles shop in San Francisco back in the late eighties. It was dirt cheap; I shoulda bought it!
