Went out to a field full of older heavy equipment today. The same place that had the Autocar extended cab truck. Took a pic. of this truck but no idea what it is.
1946 to 41-K model---8 or so, 1947 up were KB.
Definitely an IH. Easier to tell the difference between a K and KB in the small trucks due to the side extensions of the grille(or lack of)
I think that is a KB. The only reason I say that is because of the grill (unless it has been changed). There are holes to mount the chrome strips. AFAIK all of the K models had a plain grill (no chrome). I have a KB-1 that I put a center grill off of a K-1 on. So I know they were interchangeable on the pickups, I'm guessing the same is true on the bigger trucks as well??
When I go back out I'll see if there's a tag or something that could better identify it. I'll take some more pics. of the extended cab Autocar too. Lots of neat old stuff out there.
Main difference is where the badge mounted on the shell.
