Civil War era civilian powder or shot flask pewter?

Nice early Civil War or Indian War era civilian style pewter 7" powder flask with a hole or two and its been treated with something on the exterior. No markings on this example that I can see. Please view my present and upcoming political, War of 1812, Civil War, Militia, Police and Fire department, cadet, veteran society, Indian Wars to WW1 military and uniform type buttons and other assorted accoutrements. Happy bidding!
