I concur with the others -it is NOT even a FORD starter, let alone a FORD TRACTOR starter. All 9N and 2N starters never had a solenoid and used a 1-wire connection for one. This one has two posts, has TORX barrel/field coil securing screws -never around then either. The guy is obviously mistaken -he may have had it rebuilt but it was never on his 2N Tractor.
