..and they even mixed the letters. I had a 51 Farmall M, that all they casting codes were U, except for the belt pulley casting was W. All cast the same month too. I could never figure out why IH used both W and U in the same year.

Dave: I expect they may have been in the middle of some foundry changes. They might have been casting in two locations for a spell.
