Great looking truck! Welcome to the forum. My original exposure to old Chevrolet trucks was when I was 18 and working as a mechanic at a school bus fleet. We had a 1964 Chevrolet, (I don't know if it was a C-50 or a C-60.) It had what we called a "Chicago Boom" 4 welded pipes and a PTO driven winch. We had a clutch lever and an up/down lever, the PTO had no Neutral. Every once and a while it would jump into gear while driving down the road..... not good. This was a real neat truck, but too light for hauling school buses. Eventually it was replaced with a 1976 International 1810 Cargostar Cabover. This had a Holmes twin boom, perhaps just a bit bigger than the one posted here. It certainly had a longer bed. After the kinks were worked out, it was a good truck. The crazy thing was that there was absolutely no training. My training was being handed a piece of paper with an address and told that a bus was broken down there, go get it. I have a ton of stories from those days.
