- I used to have this enlarger about 4-5 years ago. I was pleased with the
- quality, amused by the manufacturer. You're right, it seemed like an odd size
- to me. At the time, though, I didn't have enough $ for another
- lens. What you should be able to do, though, is remove the
- enlarger column from the baseboard, c-clamp it to a table edge,
- then make prints. I used 6x6 (aka 2.25x2.25) at the time,
- tried a few 35mm negs.

- Make sure you take the thing apart to clean it. The entire condenser lens
- assembly should come right out. Disassemble it to get at both lenses. While
