I bought a box of random machinist tools at a flea market and a handful of these things were in there. Could someone out there tell me what they are? They have stamped on them: TRK and then a size, 7/16, 3/8, etc. However, the size stamped on them cannot be found on the tool. In other words, the one that says 3/8, I cannot find anything on the tool that actually is 3/8 of an inch. And the outer barrel of the tool can be rotated and slid up and down. Help!
