I just was given a canister of powder labeled, " Thunderbird Cartridge Co., Inc.", with 4350 printed on it in two places. It must have 8 to 10 lbs of powder in it. It's extruded, smells right and looks like it could be, well, 4350, in visually excellent condition. It's a cylindrical, shiny, metal can with a screw-cap. No date; no bar-code, no stock numbers. Does anybody know anything about this?
