The top of the board is marked "BUREAU OF ORDNANCE AMMUNITION DISPLAY BOARD MK.1 MOD.0 (VISUAL TRAINING AID)". The board consists of display rounds of 20mm Anti-Aircraft round, 20mm Aircraft rounds, .50 BMG, and other small arms calibers used by the United States Military at the time.

Very fine overall, all parts appear present aside from the tip of the 20mm ball bullet cross-section, some light display wear, finish loss, and legible markings.
