Here is one I found that is about the same size,
SPIRIT CANTEEN USED BY GENERAL HOKE.
Canteen is approximately four inches in diameter. This canteen resembles powder cans of the Mexican War and may have been previously used as such.
The Confederate Army went to war with every type of canteen imaginable. On this page I will endeavor to show a few canteens used by the Southern Army. If you want to learn more about Civil War Canteens see Stephen Sylvia and Mike O'Donnells book "Civil War Canteens" available from Moss Publications, PO Box 729, Orange County, Va. 22960.
