I think I may have answered my own question. I was surfing the web tonight and came across the IHC Mccormick collection on the Wisconsin Historical Society website. Has a page of machinery lists with production dates, number produced, and which plant made them.
According to this document, the IH Mccormick 45 baler was built from 1946-1958 at the Memphis works and 1954-1957 at another plant with designation letters HAM. At the Memphis works from 1946-1957 they produced 102,488 units and the other plant from 1954-1957, 9,704 units. That is one hell of alot of Mccormick 45 balers!
The 50T was made from 1944-1952 (8144 units), and the 55T (13,337 units), and 55W (15,842 units) was made from 1953-1959. The 50W or 50AW was listed as 1944-1947 only, with no production numbers for this baler.
Anyone else that can confirm this? How many of you out there are using any of the above listed balers? Post pics if you have them. Thanks for the replies so far!
