Used one back in the late 80's when I worked in the darkroom of a large Boston Department store. You may have been in their basement.
Nice small camera, we did stats on them, just enlarging type and small screenshots for making up ads for the daily papers. If I remember correctly, about 20x 24 horizontal glass plate for your paper, the original sat on a copy board on the bottom. Halogen lights for illumination, all done in near light conditions.
Not worth much anymore. Even as I was getting out of that business in 1989, variable type machines took over the letter press parts, and the big vertical cameras would shoot all the screen shots at once. That went away pretty quickly also.
Grab the lens, they are usually pretty high quality.
