And, of the 1,000 No. 18s made for the "Gung Ho" order, only about 900 - the knives initially issued to individual Raiders - were numbered on their blades, so it is remotely possible this knife is one of them. If not, it is one of the 5,000 Army Air Corps Survival Knives - many of which were robbed from aircraft bail-out survival kits and traded to Marines and Army infantrymen to use as fighting knives. Since the un-numbered, black plastic handled "Gung Ho" Knives and the Army Air Corps Survival Knives are identical, it is impossible to tell which it is. But, either way, it is a rare knife and judging from its condition as shown in the accompanying photos, it saw hard service during WWII.
