Anybody know who made these? I have two of them, first one I got circa 1980 at a gun shop going out of business in NY state. Second one I found in a Craigs list sale of reloading stuff. Can anyone shed light on who made these and if still available. Even better they are great for waterproofing primers ten rounds at a time as they are positioned perfectly and keep the nail polish right where you need it the whole time and there is no handling the cases until ten are finished and removed one at a time to wipe off any excess.
