The vertical tube with the row of gas jets to keep hot the side of the vapouriser away from the mantle is probably a good feature. Somewhat reminiscent of the Tilley CS56 stove, although that had three such tubes because there's no mantle of course. I wonder which is earlier, i.e. who had the idea first..?
Hi, The cleaning needle device looks for sure like Nagel Chase. Is this an India NC clone of the Nr.4 Nagel Chase lantern? Neil probably knows the answer. /Conny
It looks like a Nagel Chase number 4 lantern to me, except that this one has a pressure gauge fitted to it and it has the earlier tank with the rivets around the bottom rim. The link below shows Nagel Chase lanterns on Terry's website, Jeff. http://tgmarsh.faculty.noctrl.edu/lantern/uslantno.html
The label is hard to read in the image here but it has "Made in USA Expressly for Poy Brothers. Kalbadevi PDAO Bombay" so It looks like a pre 1920 Nagel Chase 4 because it is and was imported by Poy Bros who rebadged it. The supplementary heater means it is a kero burner. The generator heater device is much earlier than anything Tilley did. This NC4 dates from about 1917-1919 which is a few years before Tilley used the system in the 1950s. It was not unique to NC either. Several companies in the US did the same thing with early gasoline and kero models from around 1910 to 1920. NC hung on to the idea for their kero models up to the early 1930s. ::Neil::
