A used Hawksley style powder flask with copper body and brass head. The head is marked 5/16, 1/4 and 3/16 drams. The flask has a well aged patina. Overall length is 5", with a 1-1/4" width and 7/8" thick. The head is removable. The adjustable spout has some play on the shaft and should be firmer. We have only this one used example.
