I was contacted by a person stationed at Whiteman AFB in Missouri to make this plaque for a person who was going to retire. This is the Insignia of the Ammo Bomb Ordnance of the AirForce. It is called " Piss Pot " by the men in the Ammo dept. of the AirForce. This Plaque is made of Oak and Alder. It has 30 MM chrome shells on the sides for decoration. Please look at the picture that shows what the Ammo Insignia is all about.
