I have this Thomas Messenger oil lamp. I don't really know much about it, except that I read somewhere that they were made in pairs. As you can see it's in pretty grotty condition and the shade is missing. What are these worth, I've seen them sell for crazy money in the States when they are sold as a pair, but this one I suspect is a lot less. Does anyone know an expert on these lamps who could tell me more about it?
