A little ot, but while chatting with someone I got the don't you like old paraffin things question and ended up with a brass duplex twin wick lamp and milk white globe shade, not exactly a prize catch but pleasing enough for a table lamp, looking at the construction its not a modern repro, but it looks awfully late like the 1960s in construction, with made in england on the wick winder, having had a poke at google I didn't find much on duplex, but I thought I know somewhere that might. When did they stop making them? Been away a while and login didn't work so re registered, other recent projects include a 1940 pl53 with interestingly industrially repaired hood. There's always something paraffinny to play with.
Camera on phone doesn't work, was Interested in the company duplex as there's not much about, lamp description, plain dome with central seam to tank, flush slightly domed filler cap with slight knurling on outside edge, no lever on burner assembly, plain white glass globe, with clear glass chimney, its been in someone's house for thirty odd years which is part of why I don't think repro, its not my usual thing.
You have it right and as for when they stopped making them the simple answer is they haven't. ::Neil::
Yes, made until recently and may STILL be manufactured. A good quality and well adjusted duplex lamp is bright enough to read comfortably by. Replacement chimneys, wicks, burners, and glass shades are still readily available. If you intend to use the lamp regularly, get at least one spare chimney as the lamp is unusable with it. The shade is decorative and the lamp may be used without it. The opal glass globe style of shade gives the best DOWNWARD light. A clear fluted or corrugated shade probably gives the best total light. I have a duplex lamp in regular use, I purchased a new shade from John Moncrief Ltd, a company who specialise in vintage lighting of all kinds, gas, oil, and electric.
