Found this unlikely picture in the
Wisconsin Historical Images archive, probably because there's an International tractor in it. This archive contains lots of official and in action pictures of International Harvester vehicles and equipment.
Caption: Royal Canadian Air Force men using an International TD-18 TracTracTor (crawler tractor) to salvage a B-34 bomber at Shell Camp Lake, Nova Scotia, 1944.
