The Durst 606 is a compact enlarger for black & white film

Asahi Bellows Unit lens mount_NIkon S The Durst 606 is aThe Asahi Bellows Unit is a bellows for M42 thread mount cameras and lenses. Provides more than 2x magnification with 55mm lenses, according to the on rail scale; should do similar work with other lenses of similar focal length. Smooth geared adjustment, good locks. There is a tripod socket at the camera end, but it's pretty minimalist, so you may want to stick with smaller lenses. With original box.
