Cat D7 4T - NOT a Cat.

That's correct, in WW2, Cat could not step up production quickly enough, so the 4T was built, to cat design and specs, by the American Car and Foundry Company, I am led to believe that they built the whole of 4T production, but am not sure if this is true.

I remember that tractor, I was at the sale, went reasonable.

I thought that stood for Canada Car and Foundry?

Hi, OM.
I think you will find that the 'outer ring' of that symbol is ackshully a lower case 'a' - see the straight line up the right side of said symbol. But 'kee-wreck-shuns' are welkum.

Just my 0.02.

OK, I can see the "a".
Actually they had both. My dad worked for CC&F during WWII

Hi, OM.
So do you happen to know if they were separate or subsidiary/connected companies?
