I found these in a box as I was cleaning out for a move. Any idea's of what these are for ?

I cannot quite make out what's stamped on yours, but here's a John M Rogers Co. fixed caliper snap gauge that looks quite similar. (Currently listed on ePay).



Here's a Brown and Sharpe version that's also on ePay.

-They look like snap gauges to me. The stamping in the first photo looks like Betts Machine Co. They had a factory in Rochester, link below.
