I've had a 45XL stored for a few years, awaiting space for an enlarged darkroom to add it. I've got the wall mount and 2 curved arms. I've not seen it installed and not certain if I have all of the pieces, even. Does anyone have an instruction sheet or photo of the installation that I could visualize the install from? The enlarger is stored elsewhere and a bit hard to get to but I've got the mount equipment here, where the darkroom will be. I wanted to be certain that I understood the dimensions and likely mounting points to deal with ceiling height, easel positioning, etc. with minimal surprises when I actually go to mount it.
