you got FWJ, it's 12a combine wit the engine drive. I think( really foggy memory here) they offered PTO, or 2 cylinder or Wisconsin or JD engines. It would appear this one has the JD water cooled unit.
We had a neighbor that used his Ford 8N to pull it and run it with PTO, so a modern CUT of 20hp PTO should do it.
I believe they only could combine small grains ,wheat,rye ,barley,oats.
