Here is what I do know. Model 1864 TYPE II leather cartridge box with original tins. I have not, nor will I attempt to remove the tins to photo because they are in tight and I do not wish to damage anything. The US on the top was originally embossed but later a brass emblem which is an original period emblem was added on. This is a very unusual piece because the maker's mark and inspector's mark (both embossed) are located on the front of the box.The maker's mark is to the left and reads: S. The inspector's mark is to the right and reads: S. There are no other visible marks on the box. The condition of the leather is excellent for its age with normal cracking and wear and I believe all buckles, straps, ear flaps etc.
Are original and in place. Belt straps are centered, sewn and riveted. The latch tab is sewn and riveted and the brass finial is pear shaped with a point.
The 2 iron buckles are sewn and riveted. The box measures 7.2" x 1.7" x 5.2 and I believe it is for. 58 cal elongated ball but not sure if it is in fact for.
With the top flap open the box measures from bottom to top 13 3/4. Please view the photos for a closer look of the condition. The item "RARE CIVIL WAR MUSKET CARTRIDGE BOX STUNNING CONDITION BY S.
