This is a 1923 to 1925 Kitson Excelite table lamp. They are 300cp kerosene lamps with some interesting features. The generator has a built in pricker which is spring loaded and operated with a small square section brass block. I could not remove the pricker to examine the inner parts. The filler inlet valve is a spring loaded ball type held in with a spike. The air intake tube has a butterfly valve which can almost close off the tube and the upper part of the tube has a sliding cover to allow an air intake directly into the gas stream. The lamp was heavily corroded with verdigris but was otherwise in good condition and it only needed a clean, a new filler cap seal and a repack of the gland with PTFE to enable a burn. And this is how it came. There is a large lead patch on the fount side which I have left as I assume it is repairing a leak. A bit crude perhaps but part of the lamp's history and besides as the tank doesn't leak and being an idle old git I saved a deal of trouble. ::Neil::
A great find indeed! After all these years a complete example has finally turned up! This link shows a 1923 Kitson advert for that lamp and other Kitson products. https://classicpressurelamps.com/threads/1923-kitson.6460/
What I need now is a globe. From the pictures I had thought a tulip globe would fit and I have some here but they all fit Tilley and the Kitson requires a a 4 inch fitter which is much bigger than a Tilley. Still it works very well without and I can live with that. ::Neil::
It might do. The original would have been a tulip shaped globe. The fitter at the top is 4" but the bottom screen is 6". I might try a mica but really the lamp runs fine without and I have never been all that bothered about shades. ::Neil::
It's a Kitson and I have yet to find one that can't be fettled. Mind you this one does have the potential for trouble because it is far more complex than the older types. I was lucky with this one because the pricker mechanism was in good order and the generator was relatively clean. Even so I could not remove the pricker rod and spring from the generator and I suspect that could be a difficulty if the needle was broken. The pricker is described in patent GB213000 although shown in a slightly earlier lamp. ::Neil::
