I have a few dozen 50 cal ammo cans. M2A1. USGI surplus. these cans look AMAZING. hardly any wear marks, some i can hardly tell were used before. all of them came from the US govt. they have soft rubber gaskets and are new production surplus ammo cans $9 each or $8 a piece if you buy 10 at a time
these cans have date codes 2011-2016. This means the cans are not only in great condition but that the ribber gasket will seal out moisture and water for decades to come.
