As to the fronts. A was wide front only. B and BN had interchangeable narrow and single fronts, factory wide front was not available. The rear tread of the BN was I believe 8 inches narrower than the B, thus the "N" designation. The C had interchangeable narrow, single and wide fronts. Row crop only, no orchard, standard or vineyard models -- I suppose you could call the high clearance AV a tobacco model. No LPG engines, kerosene, distillate or gas engines were available. The B died in 1948, replaced by the C. The A was replaced by the Super A in very late 1947, this configuration was used in the 100, then 130, then 140, making that style the longest running IH tractor (1939-1979), essentially 40 years with only minor changes. There was an industrial A, used by many highway departments. Of the three the A was the only one with a separate industrial model, consisting mostly of a foot throttle and a heavy duty front axle. The B was discontinued mainly because of it's configuration being too similar to the A, in my opinion. My dad had two B's, one was the first sold in my home county, they were good tractors for their time period. The C was "better" because of it's easily adjustable rear wheels and higher clearance. My dad (a vegetable farmer) spent a lot of time adjusting the rear wheels on the B to fit different row widths, and also swapped the single and narrow fronts often. The A, Super A, B, and C all had the same 113 cu in engine, which evolved into the 123 cu in engine used in the Super C, Super A1/100/130/140.
