The M Farmall was before my time. How many versions were made? Obviously, you have the M, MD, and MV. And there was the Super series, and the-TA series. But in which order? Was there an M-TA and a Super M and a Super M-TA? Like I said, this was about 20 years before I was born, and some folks will talk about a Super M and an M-TA. What models were actually built?
