What I'm referring to is a cheap lead alloy that is being passed off as brass. It looks like cast brass. I can take pictures here in a little bit. It's not a die cast zinc alloy and it's not a high tin (ie pewter) alloy. It's probably 95% lead with the rest being tin. Similar to what muzzleloaders would cast bullets from. It only takes a little bit of tin to make the (mostly lead) casting look good. It's also similar to what a lot of old picture frames are made of.
