Need help - what are these?

[Cariboo Rick]

I was given these from a friend's estate. They appear to be bullet seating sleeves and stems, engraved with calibers. But what die body/press would they fit? Thanks! Rick

Quite unique looking. One way to find out what they fit is to measure the threaded part on top. If it is 7/8" - 14 TPI they will fit any standard press.

Check out RCBS competition seater.
If they are old, perhaps from a Vickers in line seater
