Now THAT'S a serious piece of machinery. Looks like it weighs five tons. I'll bet it eventually goes for less than a tenth of the posted asking price.
That's an Omega D5-XL 4x5 to the left of it (first photo) and I believe a Saltzman 8x10 to the right of it (second photo). Note the ceiling cutout above the column. Must have been a killer darkroom.
I can top that. When I first moved to this town 40+ years ago to go to work in a trade shop They made printing plates. A buddy had landed a job at the local newspaper and the powers to be decided they would start doing their own color separation So they bought with no input from any one else, a 12 x18 enlarger!!!! The news papers photographers all used 35mm SLRs He had problems to say the least!
Space is an issue. I used to have an 8x10 Devere, looked a bit like the one pictured, man it was huge. I had to build my previous darkroom around it! When I had to move, the enlarger had to go (no 8x10 camera in those days) so I gave it away!
