This should pretty well cover the 06, 56, and 66 series. I threw in the 4100, the 26's and the 68's because they were built along with the other tractors listed. This does not list any of the smaller models and I may have skipped some special model of the above listed. Hope this helps you.

In addition to the above answer, there were also industrial tractor versions of some, but not all, of the 06, 56, 66 series tractor models. The industrial models were International with a 2 before the number. For example the industrial version of the 806 was the International 2806. The industrial tractors generally had; a different grill, different front axle, different tire sizes & types, and some different standard or optional features. Industrial yellow was the standard color, however, like all IHC tractors, they could be special ordered in any color the customer wanted for a fee.

I appreciate the complement, but I am not the book writing type. I'd rather just help with information any time I can.
