ARRC, you nailed it ! I was going to say this looked liked "trench art" something handmade by a soldier or P.O.W. After reading the article, I see it's similar, still handmade, but looks like they could set up a little shop with more resources than a soldier or P.O.W. would have. Search "trench art lighter" to see more handmade lighters made in world war two.
