IH/Farmall I-404 - Other Names?

I have a 1963 IH Farmall I-404 (with C-135 engine). I hear alot about "C" and "H" tractors. I browse the message posts looking for something related to my tractor, but I never see an "I" post. Is there another name for the I-404? I mean, is it a member of a "C" class, or something like that?
Thanks... Larry

First, thanks for all your comments.

I'm pretty sure it's an "I-404"... at least, that's what the ID tag says. It was made for the military (again, according to the serial/ID tag). It's a wide-front with 28" rear wheels. I'm not sure about the tranny, I only know it has 4 speeds and unknown whether there are more or not. It definitely has the C-135 engine (I'm tearing it down right now...and it's a mess).

Some unusual things about it... 1) it's yellow (I can;t find yellow paint in any of the Farmall/IH schemes); 2) it has a super-heavy-duty dash throttle (very heavy cast metal with no wobble like most dash throttle levers); 3) it has a gas pedal too on the right side.

There is a long story behind which International Harvester tractors were badged "McCormick", and which were badged "International", and I'm sure someone will post that.

I have one of your 404's bigger brothers, a 424 diesel. It's been a heck of a good little tractor.
