FAA1 International Harvester Tractor

There are other factors with these SA1, and I starting to believe they were built from left overs. I'll give you some figures to chew on, and these only have year and month.

July 54 Super A, serial 355639 engine serial FAAM 357449. That was not the last Super A, last one had serial 355679, no engine number given. Also in July Super C tractor serial 195652 engine serial FCM 204642, Super A1 tractor serial 356001 engine serial FCM 206628. They don't say when the last SC was built, however looking at these figures for July 1,986 engine numbers separate SC at that time and the first SA1. Could it be those 1,986 engines were set aside for SC, and indeed SA1 tractors do have a sequence of consecutive engine numbers. We do know that in all these tractors engine numbers climbed at a higher rate than tractor numbers. Some have suggested it was engines going for other uses, I question that, IH sold too many stationary, baler and combine engines for those numbers to be accurate.

Then we move ahead to Nov 54, 100, 200 and I100 each started at tractor serial number 501, 100 getting engine 572, 200 getting engine 663 and I100 getting engine 976. Right off we have 71 engines that went somewhere, could it be SA1 or SC.

I'm going to get busy here, will address the other thread on serial number placement later

Problem here is this possibly a Super A1, only 1,957 ever built, probably one of the rarest Farmalls ever built. Folks do have a tendancy to try and create Super A1, as they do SMTA or SHTA. It looks to me as though someone, somewhere along the line thought they could create a Super A1 by adding a 1 to FAA. Truth is Super A1 are actually a Farmall 100 with SA sheet metal.

Super A1 from factory have, C-123 engine, water pump, The engine serial numbers are part of the Super C sequence, starting with engine serial number 206628, whereas the last SA had engine serial number 357449. Super A had serial number on left seat support, Super A1 has it on the left side of clutch housing, same as a 100.

Someone has been tampering, might be a SA1 with a lost tag and someone replaced the tag with a wrong number and stamped it 1. It could also be a hoax.

Another item you might look at is engine serial number. It's on a machined flat surface, just below number 1 spark plug. Those numbers are stamped and not cast in place. Super A engine serial numbers after June 1952 are all over 332287, tractor serial number on that date would have been 330738. According to the number you gave 331xxx, the tractor would have been built shortly after that date. Super A1 tractors shared the same series of engine serial numbers as the Super C, starting at number 206628.
