Burner is date stamped 1922. The tank was dismantled, annealed, reshaped and re-assembled. No badge on it and I can't see any sign that there ever was one but maybe it fell off. The inner reflector is a bit ratty but it is pretty sound. The outer reflector is borrowed from another lamp. Anyone fancy making me a globe cage for it so it will sit upright without the aid of a pile of books?
