The IWKOO, later catalogued as 12502, is Leitz's slip-on trumpet hood for the 21mm f/4 Super-Angulon in both screw and bayonet mount. It clamps over the front of the barrel rather than threading into the E39 filter mount, so a filter can stay fitted underneath, and the shallow flare is cut to shade a very wide field without cropping into it. It is the correct period accessory for the 1958 to 1963 Super-Angulon, and the part most often missing from those outfits today.
