Thanks everyone for the response. I bought a bunch of car parts from a guy in his 20's. All the car parts were his fathers and the guy had no use for them. He told me the tools I am asking about, were used to measure curb stones and installations. He told me some of the car parts where one thing when I knew they were not what he said, but I think it was just because he didn't know not to try to fool me. So I didn't think his interpretation of the tools was credible. Here are a few more pics. Thanks again everyone.
