Hey, Schultzie, what a memory your picture invoked!
I had one o' them Cushman three-wheelers when I was 13. It was a former City Police parking division vehicle. My first straight drive, 3 on the tree. Dad brought it home when his Blueprint Co. delivery people kept falling out of it. Seemed like a good idea. He taught me to drive it, and I used to ride the neighborhood kids around the yard with the rear cap off the bed, mostly on 2 wheels. Parents would never allow that kind of fun today, I bet! Amazing the horrors we survived.
