Not sure what this is. Came in a box of micrometers so I would assume it is some sort of measuring tool. Turning the black handle rotates the dial. Appreciate any advice.

Indeed Nicefice. I believe it is commonly used in a drill or drill press if I'm not mistaking.
I ain't nev'r sen nut'n lik dat ! I worked in a machine shop as a kid & never saw one of these. Interesting & thanks for showing/asking . Welcome to CW, aka CyberAsylum.
Thanks to Nicefice, found out this is a machinist's speed (RPM) indicator. YouTube even has a video of how it works. Thanks, Nicefice, you know your stuff !
