USS Torsk brochure and lighter

This pair of items commemorating the USS Torsk are vintage and awesome. The USS Torsk is noted as being the only submarine to ever sink a train (yes, a train) as well as having the last two confirmed fatal hits to Japanese ships during World War II. 

The lighter is a Vulcan casing with Zippo fuel tank. It features the USS Torsk emblem and submariner emblem engraved into the lid. Circa early 1960s, and very rare. 

The brochure has a copyright of 1980 and features the heroic story of the USS Torsk, as well as a general schematic of the submarine. Very cool, but very delicate.
