Genuine U.S. Army issue Ordnance Corps Guidon flag.     NEW, Unused condition.     1986 vintage.    Ordnance bomb symbol is sewn onto both sides of the flag.     Over the past 3 decades guidons have been made of 200 denier 199% nylon instead of the older style nylon-wool.     This flag is made of the older nylon-wool material.     Color is yellow flaming bomb ("flaming piss pot") on red.     The field is regulation 20-inch hoist x 27-3/4 inch fly.     Standard 10-inch swallowtail (forked) fly end.     Since this guidon has never been used by any Ordnance unit there is yet no numbers or letter attached.
