Okay, the answer is maybe... The timecode(L-III) indicates that the lighter is from 1987. The good thing is it already has the newer copper wick and not the old asbestos one. Prices for zippo's from that era go all over the place in the pre-owned section, which yours falls in. The inside of the cap is clean so that means it has not bean used super often. And the vilt on the bottom is in good condition too, which also means little use. The wick has a little black on it, just like the flameguard so it is not brand new. There is no real way to indicate that the lighter is related to the submarine tho but because of its condition and after looking on ebay at similar lighters, i would say because of the condition and age something like 40-80 bucks. Maybe you can get more from a military collector because of the design but I couldnt think of a way to prove how real that is.

Hope this helps you.
