1945 US Navy WWII Replacement Sample powder Tank

dated 1945, U.S. Navy Powder Tank MK.1 . Shows a U.S. Navy stamped. Inside is as clean as can be expected for this 62 year old solid aluminum canister. Was made to hold bags of gun powder. I have seen the tall ones, but this is the only short one (9 inches) I''ve seen. If I had any GOLD I would keep it and bury it in my back yard. Will never rust.!!
Rare find
Any questions please ask, thank you
