Default Another dumb question?

Looking at flathead engine specs, I noticed that with the exception of the '34 ford (40A) there is no A at the end of the model #s Till 1938 (81A). Then they all end in "A" until 1949 (98BA). What does the A stand for and what does the B stand for? Terry

For the earlier models ('38 thru '48), the "A-" after the numerical model number ("81A-" or "01A" as examples) means that the part is intended for "Passenger Car" and "1/2-ton" pick-up trucks. An "81C-" or an "81T-" indicates a part intended for a COMMERCIAL vehicle (81C-) such as a Panel Delivery, or a BIG, heavy duty truck (01T-).

On 11/20/1948, a U.S. federal trademark registration was filed for FoMoCo. This trademark is owned by Ford Motor Company. This brought many big changes to the way Ford Motor Co. (Now FoMoCo) did some things, like in their parts numbering system. This is about the time that more and more coded LETTERS became the norm in part numbers. But I still have not figured-out what the "BA", or in the case of Mercury, "CM" means. DD

Thanks Coopman. You helped a lot 'cause I didn't even think about the "C" And "T" letters either. Terry
