The interior frame measures 20 13/16 wide by 32 3/8 tall inches with the exterior measuring 25 3/8 wide by 37 1/8 inches tall and the display is approximately 4 1/4 inches deep. This impressive board includes an assortment of rimfire cartridges, centerfire cartridges, and shotgun shells ranging from the tiny BB cap up to the massive 1 inch Berdan Gatling. All of the cartridges are neatly arranged in rows and labeled in gold on a dark navy blue background. "AMMUNITION/MANUFACTURED BY THE/UNION METALLIC CARTRIDGE COMPANY,/BRIDGEPORT, CONN., U.S.A." is arranged in four lines at the top with a U.M.C. monogram logo to either side, also in gold. The frame has two black accents that run around the perimeter and a pain of glass protecting the entire display. This is an exceptionally rare cartridge display with very few examples left known to exist, one being in the Smithsonian and one at the Springfield Armory Museum. It is possible that this is the only example known to exist with the navy blue paper background.
