Been trying to buy this "ol M for the last 20 years. Finally got it bought!! The man said it was parked at the end of the field because the transmission locked up. Went over Monday, pulled the gear shift lever out, shifted it into neutral, jacked it up. The rear wheels wouldn"t turn, ice in the rear end. Only about 20 miles away. Went over with loader tractor, bumped the rear wheels, she broke loose. Picked the front end up with the 3 point and headed for home. Not sure what to do with it now. Motor is stuck, but cylinders are nice and clean. Got it soaking now, with the head off. Has the 4 inch dome top pistons. Time will tell.
