I think that deserves a two-syllable Day'um, as in "Day'um that's a huge camera".
Too bad there's no darkslidey kind of arrangement to be able to wheel it around loaded and use it in the light. 1:1 portraits on 16x20 would look great.
An awful lot of electrons were terribly inconvenienced in the making of this post.
It is a process camera. It is a little strange to see one on wheels, but otherwise they were very common. Any print shop that produced work with an offset press might have one.
In my youth, when I was shooting 35mm film, it was fun using the process camera in my high school's print shop.
“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”

Yes, it's a process camera. In my experience the back of the camera was normally built into the wall of the darkroom. I'm a printer, and haven't seen one in many years. I once had a smaller vertical one (like an enlarger) that I tried unsuccessfully to sell, then give away, about 15-18 years ago. I finally just put it in the alley behind my shop - it was still there when I moved about five years later, although someone had taken the lens.
