Vintage Lighting Trying to figure out what fixtures used BRN lamps

At my theatre we've been cleaning out our lamp storage, and came across some lamps that we aren't sure what fixture they might have gone to.

They're an ANSI code BRN, 1200w lamp. I can't seem to find any details about what they might have been used in. (Also it's really hard to find anything when the thing you're searching is also just an abbreviation for brown)

There seems to be a reflector of some kind behind (I'm assuming behind?) the filaments. The base is definitely set up to only be installed in one direction, it's got 3 contact pins and a central post.

POSSIBLY the Buhl 1200 Watt 35 mm slide projector &/or POSSIBLY large beam projectors. Someone made a 1200 Watt follow spot as well.

Those are retrofits for an old style incandescent.

Now what takes one of those is another search.
 
With the addition of the Buhl slide projector to my searching, it seems like this is the most likely thing. I've managed to find a listing on Canadian eBay for one of these lamps that says some of the slide projectors that it's compatible with.

I don't think we have any of those models in the building at this point. Our storage seems to only contain Kodak Ektagraphic III slide projectors, and those take a very different style of lamp.

Thanks for the help all!

@DanielJC The Buhl's blew so much cooling air through their gates that cardboard slides would flutter without fully landing. Glass slides were required for successfully reliable operation. A dissolving pair of 1200's appreciably raised the ambient temperature in your booth. Two dissolving pairs for two screens was both too hot and TOO noisy.
Toodleoo!

Kodak Ektagraphics were the mainstay slide projectors, but they weren't terribly bright when used with a long lens or a large screen. I think they typically had an efficient, 300 Watt, reflector lamp. The extra horsepower of the Buhls were probably needed for really big screens and l o n g lenses. Maybe there were higher output Kodaks, but I never encountered any.

One time, I had a pair of Ektagraphics for a show and wanted a little extra punch, so I put them on a variac and cranked the line voltage up to 130 V. They were rentals, and I had extra lamps.

I owned 10 Kodak Carousel AF2's. From the crevasses of my mind, I recall the standard lamp was the 120 Volt 300 Watt EZK; there was also the very similar 120 Volt 300 Watt ENG with an appreciably shorter life span pushing out more lumens.
