Been fettling this old FL2 for past few days its not my lamp just doing some work on it for a friend. Its a rare piece so needs documenting here. From around 1931 it has the single tube burner as other early floodlight has.. It has a registered design number stamped on the brass frame bit hard to photo but its RD. 762129 which is the same as later tilley flood lites have so what have they registered could it be the reflector? i just dont know. I cannot think of another manufacturer that made a floodlight projector maybe you can? Its in really nice condition now but the reflector has lots of marks but still knocks out a nice bright light cheers pete
