I have a .58 cartridge box for sale. I bought this from Don Smith of Trans Mississippi Depot a while back. Below is the description that he listed when he offered it for sale. Made very well like all of Don's stuff, still in great condition.
"US M1857 Allegheny pattern .58 Cal Rifle Musket Box, made by TMDCo. Modified to meet 1861 Ord Specs. As seen in Paul Johnson’s book “Civil War Cartridge Boxes”. Box is made by T.M.D. Co. Rivets were added to the belt loops to re enforce them, as seen in Mr. Johnson’s book. Box is in good condition, well cared for, comes with tins"
I'll take what I have in it, $100 + shipping. I accept paypal.
