Thanks Ron, I did not know this; Incidentally, I had a Starett thickness gauge for twenty-five years , before it wore out, and then acquired the Mitutoyo. They are almost identical. I only use it as intended.

You don't need a super precision lab quality machine to grade felt. A tire durometer, from a racing supply house, is a Shore A scale and cost about $60 USD. Since we don't order anything by durometer numbers, we're just taking comparative readings and that's a good enough tool for our purposes.
