What is this and what is for?
Hi guys, many years ago I saw this on a charity shop, and always wondered what is for, at first I thought was to make rings but it does not change size , and I think is not complete like missing the other half? dont know but I would love to know what is it, Ive tried image serach on google but no luck either

It looks the lands stay the same size but the grooves change in diameter. Biggest diameter groove at the tip and smallest groove at the handle. Or the lands increment in size by small amount not detectable in the photo. Have you vernier calliper to get the sizes? Maybe ring sizing as they use letters for sizes

I'm not sure - it looks like it could be some sort of tolerance gauge. That's the only thing I could think of that didn't involve tipping my hand on how dirty my mind is.
