Rolleikin 2 kit. Complete, with screws. Looks unused except the frame counter was once mounted on my MX-EVS Automat. Nice leather case embossed "Rolleikin 3.5" but will work on 2.8 models as well- according to John Phillips' book. Asking $49 plus actual shipping.
These are nice. I remember the days when itinerant portrait photogs used these on a Rollie with Kodachrome film. The Rollekin gives you the 35mm portrait format and a 75 or 80 mm lens on 35mm, and you could sync at 1/500 of a sec. with the Rollei whereas most 35mm cameras had a slow sync setting. And Kodachrome gave you great images at 35mm prices.
