I have cleaned several Kodak Duaflex cameras with Kodar (two-element) lenses. There is a pressed metal hold-down with an odd-shaped hole which causes the front focusing ring to grasp the lens to turn/focus it. I have had one come off (for the life of me, I don't know how) and cannot figure out how to get it back on. Any clues?

Finally figured it out. Unscrew the lens, place the hold-down back in place. Then screw the lens back in 1/4 turn increments by turning and resetting the hold-down.
