I always pictured some third-world factory still ripping off clones of some of this obsolete equipment, kind of like they still make old VW beetles in Mexico. Who was the last to produce carbon lamps and where?

Strong was probably the last since the strong 1K and the futura were the lamps on the back of a super trouper and gladiator followspot
I believe the magnArc was still available new into the early 70's
Pat could probably tell us more about that
In India Monee still has a magnarc knockoff available

John Mellor:

Check out the National Projector Carbon Bulletins that are in the Film-Tech Manuals section. Lots of discussion and photos of condenser type lamphouses.

Just about every booth I was in (in the old days) had a big bucket of carbon drippings. The regular projectionist always had a story about how he was gonna be rich from selling the drippings. Did anyone in these booths actually sell the drippings? Or did they just get demolished when the building was condemned or turned in multi/mega-plex?

The theater was supposed to cash in the copper, then donate the money to Will Rodgers. But, I'm sure you will not be surprised when tell you that many times, that did not happen.

An older guy I worked with was *nuts* about getting and selling copper. He would actually keep track of stubs, and many times would declare a 6" length "used-up." I would work on little electric "booth-projects" and he was always asking; "Are you going to use that peice of wire... it's too short for anything..I can have it, OK..?" He would sit there with a pen knife, peeling away. Then, he would just thread-up; never washed his hands until he went home.

Sorry, but it drove me nuts, as you can see....!

National Carbons are still manufactured and sold in the US by National Specialty Carbon Co. They use the trade name 'National' This division was split off of Union Crbide many years ago. The theatre projection end is not as busy as their medical and printing divisions, they make carbons for X-ray & photo exposure lamps, Printing plate exposure, and other uses as well as searchlite carbons. National is alive and well! I still sell several cases a year to
a select few customers! They are still more stable and emit less shrapnel than Marble or
lesser brands!!!

Unfortunately, the current National doesn't make anything smaller than 8mm. I'm in desperate need of some 6mm pos. and 5.5mm neg. Pearlex to run in my 16mm Victor model 1600.

Does anybody know if Marble, or anybody else makes anything that small? Even if I can't find the Pearlex, I'd settle for anything in the correct size.

No, I don't really run the Victor that often, but when I need it... it's the only thing that does the job. It's great for the occasional outdoor party. I probably have more FUN running it than anything else (except a AA-II).

I still have access to a number of tubes of NOS National Pearlex 5.5 & 6mm paired sticks in the round tube. Email me for details.
