I'm just putting this out in the shop. I was researching it last week and was very surprised to see one coincidentally pop up on the Antiques Roadshow. That one was hallmarked silver made in England in 1875 and the silver expert didn't have a clue what it was. Someone was sure that it was a lace making tool and that her grandmother had one! It was actually a copy of a Japanese fold up portable candlestick. The one I'm putting out is brass and a bit smaller but like the silver one is missing the little tray to catch the drips. I think they're often missing because when it's folded up it just sits in the round hole and would be easy to lose. It was invented in 1834 by Tanaka Hisashige a prolific inventor and one of the founders of Toshiba. An interesting addition to a collection of curiosities - or you could make a new drip tray and take it on camping trips!
