trying to find a year on a mccormack A

Mark in coulterville · Aug 16, 2009

Hi Everyone!
I just bought a A from my neighbor and He is not sure exactally what year it is. Yesterday I went to the thresherman show in picneyville Ill looking for answers There I found a 1941 A and spoke to a man who showed me the date code. However he could not tell me what the last letter meant( the year it was made)on the 1941
it is straight across and on mine its at a 45%
angle which suggests to me its a later model
mine carries a code of 4-10-Q or O its a little hard to read can anyone help me figure this out?
thanks ever so much Mark

WHAT are you getting at with the "45º???

"Q" = 1947 in IH casting code parlance.

So that part was CAST on April 4, 1947, later machined, and still later assembled as part of the tractor, from a month or so to perhaps a year after the casting date.

Have you looked for the SERIAL NUMBER plate riveted to the LH seat support?

P.S.... casting code "O" would be 1945.

O would 1945 P-46 Q-47 Which is the last yr of production it was replaced with the SA with the first of made in 47.
