What type of dies are these?

[Meta]

I have a bunch of these dies purchased in a large lot from an estate sale and can't identify them. They won't fit my press (rcbs) as they are meant to be threaded in from below, not above, and therefor don't leave enough clearance. Any guesses on what type of press these are compatible with? Thanks!

Looks to me like a normal die somebody put together the wrong way.

Unscrew the expander / decapper stem out of the die and screw it back in from the other end.

Yep appears to be upside down. The innards need reversed.

Nope, that's what I thought initially. Have a look at another pic.

Older where top does not move.

I would guess one of the old presses with a cantilever arm on the bottom table that lifts the entire floor platform onto a solid top. Would include CH, Texan, and early Pacific from about 1964 and before. Some of those very well made machines and would last as well as those dies. The 257 Roberts was a hot ticket in those days.

That's definitely different
