This Zippo was produced 1950/1951 and shows a beautifully engraved landscape of Japan. The US soldiers who were stationed in Japan after World War 2, the engravings of locals were engraving. The letters W.S.B. are the initials of the former owner. Unfortunately I have no information about the US soldier. The Zippo is unused and in box. A beautiful and rare Zippo with historical background.
