Non veni pacem mittere, sed gladium.
Sorta looks like it, but the ones in my neck of the woods weren't semi's.
Looks like a Marmon.
It's a Diamond-T with the International Harvester "Comfo-cab". They had that cab until the White Motor Company bought Diamond-T, merged them with REO and used the White "Drivers Cab". That merger produced the Diamond-Reo. Picture looks like it was taken in the Okanagan Region of BC in the late 50's. Gorman Bros is still operating there.
Great info, C-Warrior! I appreciate the additional knowledge, and I really like that Gorman is still in business. Diamond T was a top of the line truck, and it probably lasted longer in that rough business than lesser trucks. Another great old brand I wish was still around.
