An odd coincidence.
Years ago, as a commercial photographer, I photographed the Fotar horizontal enlarger at their factory for their sales brochures. Sadly, I can't easily put my hands on the tranparencies or I would post them for you. The horizontal was used for doing BIG prints, required a lot of space and would probably be inconvenient for normal enlarging
The horizontal that I photographed was nowhere near 8 feet tall and it projected on the wall. From the description, it sounds like they may be referring to the Fotar vertical 10x10. I have used this enlarger extensively at a couple of different labs. I loved It. Their stuff is superbly made.
Definitely get more info
