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.
