Looks to be between June of 30,when that round cab came out,to about June of 31,when than narrow bed was replaced with the wide bed.Drove that same truck for about 25 years,then replaced the cab with an open one.Still driving it.
Tires are still good, can't see the air in the tubes yet.
My dad described getting more miles out of tires during the depression by fitting a used tire from a junk yard over the one already on the wheel. He said the problem was that little balls of rubber would form between the tires causing the outside tire to slip on the inner tire which made for bad braking.
Yes, I thought about that. They may have been clincher tires that stretch or maybe larger tires. They probably took the air out of the one that was mounted on the wheel and then blew it up again after the outside tire was mounted. My dad crossed the US with some other men in a mid 1920's Chevrolet during the Depression to find work out west. I only have the two stories, the one about the tires and another one about fitting a rod from a junk yard. It was fit tight and then broken in by driving the car.
Did anyone notice the "Devil" radiator ornament on the roadster behind them? I thought for years the repro Devil giving the "thumb to the nose" ornaments were a thing of recent imagination. I guess not.
