A used Durst Laborator 1000 enlarger head with a Durst cold cathode light source, Otoneg 2 negative carrier with 35mm masks. Instructions for the Laborator can be found online. The lensboard has a Setopla lens mount which takes 39mm enlarger lenses, but happens to have a 25mm fitted to it, so enlarger lenses with both 39mm and 25mm mounts can be used.
