A friend gave me some brass a couple of years ago. It was herters packaged, in boxes of 20. the box says match grade, made by the best brass manufacturers in the world, and has made in sweden all over it. It was new brass, but very old at the same time. there aren't any lot# on any of the boxes. Just wondering if this was actually made by Norma, I hope!! does anyone have any clue to this?
