Well, the Unicolor enlarger I used when I was in high school is now in the trunk of my car. My father actually had the lens, elcheapo Unicolor 50mm, saved safe and sound, and knew where it was!!! It turned on, has the negative carrier, 35mm only, and after I cleaned the soot off of it, 20 in an attic, lots of ick to clean, she looks pretty good. Now I have 2 enlargers. I have to focus on the easel and timer, Nikkor lenses are there to be had at any time from ebay.
