Check the listing for details. WW2 US Navy Powder Can 1945 Dated USN Airtight Aluminum. Condition: Used, Made in United States. Listed at 37.99 USD. This is a vintage US Navy MK.I Sample Powder Tank. These tanks were used on ships during World War II and the post-war era to store samples of gunpowder. The purpose was to expose the powder samples to the same environmental conditions (heat, humidity, motion) as the powder loaded in the ship's main gun cartridges. Periodic checks of the sample ensured the main powder supply was not deteriorating in a potentially dangerous way. The tanks were typically made of aluminum and often dated with the year of manufacture, such as 1945. They are now considered historical military collectibles. 15 inches tall
