In the small darkroom/developing room:
SAUNDERS LPL SUPER DICHRO 4500II 4x5 ENLARGER. Here is a link to the instruction manual in PDF form. It is a $2k enlarger. In my mind, is the nicest 4x5 enlarger ever made.
NOTE: You can't use film chemicals for processing prints.
In the larger darkroom:
There is a Beseler 23C (the blue one to the right), a 23CII (the black one in the middle), and a 23CIII-XL (the one with the color head and extra tall column on the left).
Never force anything in the darkroom. If you do, you will break it.
