I’m drawing a blank. What is it?
I have no idea. But if there is more than one engine, the left one is pretty far out on the wing. Water cooled. With the low hung prop probably fastened directly to the crank, thus a low RPM motor.
The cowling reminds me of the Oliver super 88 tractor my dad had when I was a boy. (Was 8 yrs old pulling the hay baler with it, while my uncle supervised while loading the hayrack behind me. They both passed away last summer)
Junkers F24, I think. Ping to #19
