Any of you fellows that have been around awhile have any experience with Herter's Model Perfect Primers? I just found 1000 of them, The outer box is a bit shop worn, but the inner boxes are still pretty crisp and the trays are plastic. The anvil only has 2 holes instead of 3, is butterfly shaped. The Herter's address has a zip code, so they must be post 68, or whenever that started. I tried Googling the Japanese maker to inquire about the lot#, but only got 2 hits and it's some old stuff, long gone company I guess. I'll try them next reloading session, they have to be better than match heads!
