At a website I write for, a reader sent in a photo of a brass tool, wondering what it was. I'm sure somebody here knows!

I have noted that the graduations on the item are radius vs circumference -- r of 4/3 is a c of about 8, r of 3 is a c of about 18.5, etc. It's to inexact to be a machining tool, and the points at each end are interesting. Any thoughts?
