This is an interesting marking tool, I would like to find out what is used for.
The numbers on the marking tool do not show well, but I wrote them down.
Another unsolved mystery | ||

I believe I was correct on the original post. Now I see it closer I will post a link for you that may explain better than I can.

Be aware that the one in the link is newer and has less calibration but they are basically the same tool.
@fhrjr2 Thanks for your help but this one piece is different than the first picture I posted, and the shape of the first post is conical.
I understand the shapes and they are all I.D. measurement plugs. I will give you an example of the conical one. Have you ever seen the measuring rod a jeweler uses to measure the size of a wedding ring or other ring? You need to measure the inside diameter and that is what each of your items is for. Each has a different application depending on the calibration of the individual piece.
