farmall f20 magneto

Just bought a 1939 farmall f20, looking it over notice it had a american bosch magneto. Was wondering if that was a conversion for it or if it was original for that year. I know most of them took f4 mags.

The Bosch FU4 Magneto was optional "Special" equipment on the F series. Great find, very few of them around. I would keep it on there for sure.
If this is a running tractor keep the mag well maintained, if not I would rebuild the mag before ever putting it into service 1 bad bearing in there.... bad for the mag, or a sticky impulse.... bad for you and your arm. Send it to Nebraska Kirk for a rebuild.
