The Classic features high smooth polished brass, or brushed brass, while the Tumbled Armor is crafted from thick, Amber-colored, tumbled brass that features a distinctive bottom stamp, authenticating the lighter as heavy-walled Armor that is 1.5 times thicker than a standard brass case. The 1941 Replica is also crafted from Brush Brass, but has flat planes with sharper, less rounded edges, Additionally, the lid and the bottom are joined with a four-barrel hinge and the inside unit is flatter with squared edges. This drop highlights a few new styles, to boot.
