I don't know if this is a model 1215, 1217 or some thing else. I hope some one will sort that out for me. This lamp took more time and effort to get going than any other lamp I have worked on but absolutely worth every bit of it. Takes a bit to get going but once hot it is stable and bright. Absolutely, positively one of my favourites. The pricker shown here did not work as the pointed bit was too long and folded over. I made up another with a shorter point every thing went perfectly.
We don't have model numbers for any Barnard lamps. They are sort of copies of Blanchard product and as such this is Walter Barnard's version of Blanchard 1215. Walter worked for Blanchard until 1925 and we think he began making his own lamps after Blanchard changed ownership then. As these are pretty well hand made lamps serial 360 is probably from the early 1930s. Always tricky lamps to fettle but such a good burner that they nearly always run well. ::Neil::
To make life a bit easier for anyone else I thought I would add a few points. To get the jet out I got a 9mm socket and turned it down to fit into the burner head. The wall of the socket got quite thin as can be seen in the pic and I wouldn't want to go any thinner. The packing that came with it was a very course mesh and blocked. I tried the same mesh back in it but it roared like a flame thrower. I tried a few others but ended up with a very fine mesh poked into where the arrow is pointing. Making the wad long enough to be able to grab it with pliers of course. The fine mesh is I believe #80. Diameter of wire = 0.14mm Distance between wire = 0.18mm 38% open space. The mantles on it are Butterfly 500/600cp tied onto the flame spreader.
I have been informed by a very knowledgable Blanchard collector that this is indeed a Blanchard made by W. T. Barnard early in the 1930s before he started to add name plates to the fuel tanks and it is model 1217.
