Here is a neat old piece. This is a Champion Spark Plug Tester from 1936. It uses a model T coil inside. It is missing the gauge that would show how much pressure was in the chamber. The pressure was used to simulate the combustion chamber pressure so you could see how the spark plug performed under pressure. There were adapters so you could check different types of plugs. The only adapters with this one are on the plugs. I have not tested or opened it up but it sure would be neat restored or to be made functional again. See the link below for more information.

That’s a neat one. They look like this fully restored.
