This might be worth a look.

“Hobart DC welder from the 50s powered by a 4 cylinder CJ2A jeep flat head engine and mounted on a 2 wheel trailer that fits Chrysler rims. Item has been stored in a garage for around 25 years after being taken out of service due to a leaky gas tank. The cables were scrapped due to the insulation all falling off of them years ago. The trailer tongue has a single hole in a flat strap cut with a gas torch.
The engine is stuck from sitting for years but should not have gotten any water in it.
I have a key for it that fits the switch and moves between positions.”
