Fantastic lamps, John. I'd like to suggest a miner's Davy Lamp if you are thinking of adding to the collection. (My father and grandfather were both coal miners in South Yorkshire, so this occurred to me immediately.)

There are many variants, but to me, this one is the classic. Lots of references available with a picture search for "Davy lamp". I think one of these would work in a number of settings, not just down t' pit!
