I recently bought a .30 cupfire unmentionable which has provoked me to become even more interested in the cartridges for it.
My question is what variations of cupfire ammo are there?
I currently have a:
.28 with no hs
.30 with no hs
.30 with raised P hs
.42 with no hs
I am pretty sure that people collect these based on obviously different HSs, but also different depths of the dish in the base, as well as different locations of the case crimp.
I know these were made by Phoenix, American, Fitch, Van Vechten. Who else is known to have made them? I have seen cartridges boxes that say made by Plants Manufacturing Co. Did they actually make cartridges or contract them out? I know they made the unmentionables but am not sure if they actually made the cartridges or not.
I know there is a .30 cupfire with a raised A which I do not have, are there any other headstamps for any of these sizes other than the A and the P that I have?
