Divco Delivery Truck
When I was a kid, I helped my Dad deliver milk door-to-door in one of these (maybe this one, I don’t know). He stood up when driving. The gas on the right and the left pedal was a clutch/brake combination. When he pushed down on the pedal he could shift gears, push too far and the brake engaged. I stood on the right side trying to keep my balance with my fingernails grasping the little desk thingie. No such thing as seat belts, air bags, etc. The box was not refrigerated, so he loaded the truck with products, then shoveled ice chips on the load.
