I have had this for quite some time - back in the days of 'Banzai Magazine' published by Louis Demers in the 1980's, this was referred to as a Combined Operations Boat Troops insignia, but I see it pretty much universally referred to now as an Army Boat Crew insignia (ignoring those who refer to it as a Navy Pilot Wing). Woven in 'Bevo' style, in unissued condition.
