Never seen those before but they do look like some of the old NDFS dies that screw in from the bottom of the press not the top, after that they works just the same.

Roundnoser is the resident Potter expert around here. I'm sure he'll be along shortly to tell you how they work. He has a website on Potter equipment: http://www.potterreloading.com/
Hope this helps.

After a shooting spree, they always want to take the guns away from the people who didn't do it. - William S. Burroughs.
they will not fit in a standard press, AND they neck size only. Potter made a few different presses. One has a priming station on the left side. It looks like you have the priming anvils for that operation. Do you want to part with those dies? if so, shoot me a pm
goblism,
I sent you a PM - As ReloaderFred mentioned, I am the site owner of Potterreloading.com. Those are Potter dies. They are 7/8 x 18 thread and only work in Potter machines. If you are thinking of selling them, I would be interested. -- Thanks.

That's the first I have ever heard of Potter dies, How long have they been around?
About 80 years
