M.M.B. 12-92 Pilots Survival Knife

Sir. A quick internet search indicates this blade has been in in service since the mid 1950's. Thousands made for military. It's been made by several companies under several different military contracts. Being as the " some information" of your post is extremely vague its hard to be more helpful. For specific Intel on the blades manufacturer look on the Ricaso area.
sir. Without a picture no sound minded person is going to make a guess to its true value. you'd have to consult a military memoriblia expert.. Earlier I said thousands made. In reality its more like hundreds of thousands or millions. A new one cost around 50$. Used on ebay.. 20$ to?? ?.. depends on what you want to spend.
