This is a very nice piece! It is an original Civil War soldier's cartridge box. This is the classic .58 caliber style that was so heavily used during the Civil War. The outer flap still has the very nice original "US" cartridge box plate present with nice clear lettering. The outer flap still retains the original closure tab that goes over the brass finial on the bottom of the box. When you raise the outer flap, you are greeted by the inner flap of the implement compartment. The inner flap has the remnants of the Civil War maker mark of H.W. Oliver from Pittsburg, Pennsylvania. According to the maker book Oliver only had army contracts for cartridge boxes in 1863 and 1864. That lets us know that this one is definitely a Civil War production cartridge box. The innermost compartment has the original tins intact with a fine look. On the bottom of the box it has both of the original roller buckles intact. On the back of the cartridge box it has all of the original straps intact. These straps would've allowed the cartridge box to have been used on a belt or with the shoulder sling whichever way the soldier preferred. The leather has some chipping but it still displays well as you can see. This is a fine displaying cartridge box that will look great beside your Civil War rifle.
