Anybody know what these are ...Swage Die Parts ?

[PapaJ]

They appear to be some kind of bullet swage die set. They resemble some of the Corbin swages I've seen online. I know that you can form an actual bullet with them, as there are parts to compress/form the tip as well as the base.

The die appears to be what is called a "SWC" die, it has bleed holes to bleed of excess lead when swaging the boolit. The base punch with the small dimple in the center is used to make a "base guard " boolit, similar to a gas check but supposedly scrapes the bore clean with each shot fired. Also looks like you have a button nose punch, a swc nose punch, and a round nose punch. The other base punch looks like a bevel base or possibly a heel base punch. Just a wild guess but I would say they were made by one of the Corbin brothers, possibly Dave Corbin.
Do you have the press that fits these dies? a pic of the press would help in identifying the maker.

PapaJ,
Welcome to the forum.
I moved your post to a better section and will be likely viewed by knowledgeable members.
I also added more info to the Title, so it's more search friendly.
Good Luck.

That is a "M" style LED (lead extrusion die) with 5/8" x 24 tpi. Used for swaging pure lead bullets. The holes in the sides allow excess lead to be bled off.

Corbin made a Silver Press that used this style of swaging dies, Blackman presses also accept this style of swaging die.

The longer punches go inform the bottom of the die, and is referred to as the internal punch, the shorter punch go from the top and create the bullet nose shape.

FWIW.

Unfortunately, I do not have the swage press. I may buy one though. I picked these up in an estate lot. Since the die body has different threads than standard 7/8, I'll probably have to have something made/machined so I can use them unless I buy the actual press.

Those dies are made for the Dave Corbin CSP-1- S press like the brown on on the right that has a case stretcher I made for it. The Blue press id a Richerd (RCE) press and it has 7/8X14 thread dies.

I agree, it looks like a Dave Corbin S die and punches.
