At the time of this aircraft being produced, henry was trying to purchase Isotta Fraschini but the deal was denied by the Italian government. That's a fact. Now for the guess: Isotta Fraschini Asso 750 engine of 800hp. Same as used by the SM S-55 seaplane.(a V-12)

Looks like a single-engine version of the Ford Trimotor, probably with some kind of V-8 or V-12 engine, based on the design of the cowling.

Interesting plane. Ford's thought for a single engine cargo plane. Don't recognize the engine. Believe it went off to Alaska Airways and eventually to a mining company in Columbia.
