Now that would have been a neat find. It's a shame this light is probably no more. I believe the 3ft T17 was only made for a couple years during WWII and so are a lot rarer than the 5ft T17s.
Yeah my understanding is that it was only made for a few years in the 1940s and was "temporarily" discontinued due to supply shortages and never made again. There's a couple of examples of this lamp on LG. No pictures of the fixtures or the gear though.

Yeah very rare lamp. One could only hope for a cache of these to emerge from a dusty warehouse lol. If they do, prices probably won't be cheap.
