Here's a couple items I picked up yesterday but got a question about the IH wrench.
I looked for the M in a square logo but came up empty so could this be a owners mark along with the 7 to the right of it? the wrench is 9 inches.

Looks like an IH logo to the left of the M-7.  Paint is concealing it abit.....or am I totally wacko here???

IHC did make a model M engine. Dunno if this makes any sense tho....

 Would guess that logo is a foundry mark. Have a IE size with similar mark. 7 probably first part of 7E size designation. On my 1E the 1E is on opposite side but they did it both ways.

There is something on the opposite side of mine too, didn't think it had anything to do with the maker though. guess I'll have to check in the morning.
