TIM, when you said it was a model 105 I'd have guessed it w shop got allas built in 1968. I would have missed the month.
IH was really good about building to a schedule, and a Mixed Model schedule at that. I worked at the FARMALL PLANT in Rock Island, Ill, we built large ag tractors 2wd and 4wd with only limited shared parts. And we kept several IH plants and foundries humming building tractors. Farmall had it's own foundry that made lots of castings but that was closed around December 21, 1967. The other IH foundries all competed for that work. IH Louisville, and IH Memphis, and IH Indy. A few outside foundries made parts too. The Louisville Forge shop got all the forgings. In about 1987 I attended a mandatory meeting for all Farmall employees where our plant manager said if FARMALL alone could run full bore it would do enough business with all other IH plants to make the whole corporation profitable.
