Uzi dies, .25cal ACP Model B

Hey guys this is my first post in this forum so thanks for having me...

I have some dies and am needing them appraised, they are for a .25cal ACP Uzi Model B. The dies were made in my great grandfathers machine shop, he was a retired Indianapolis Police Officer who turned his gunsmithing hobby into a career after retirement. Anyways, I have his dies and want to do something with them but am not well versed in machine work or what it takes to make this kind of stuff.....any help would be greatly appreciated
