Congratulations on a fantastic find!

I’m going to have to agree with Gil on the age of the engine though. Everything about it says early post war. The generator with the lamp post on the base is most definitely post war. The cord is typical of all early post war engines. The whistle handle is also typical for a post war engine. The earlier 1930s handles were a larger diameter and a rougher finish. The flare on the stack should be at the top just like all Jensen stacks. The sight glass assembly on this engine looks suspect to me. It appears to made from commercially made brass fittings. I see no reason for Tom Jensen to use bought parts at that time when he had been making his own for a number of years already.

You mentioned in one of your videos that an engine was purchased in 1938 and another was purchased a few years later. I think it is more than likely that the previous owner has gotten confused about which engine this one actually is. This engine fits the timeline pretty well to be the second one purchased.
