A 1905 Starrett gauge, but what is it?

Admittedly, I own a select few inherited tools that I have no experience with. Here’s an antique Starrett tool that has me wondering: What is it?

While cleaning my shop this week after using the destructive, chip throwing “Lancelot“, I found this tool on my top shelf (yes, unfortunately, wood chips covered everything, reinforcing the notion of using my “assembly table” for assembly only.)

Can I assume since it’s Starrett that it’s for measuring? Sure, it’s got a rubber wheel that when rolled, turns a dial that is labelled from 0-100 with inexplicably odd numbers at each mark around the dial: 19,28,37,46, 55… – I see a pattern here.
