This camera is a bit of a hodgepodge. The normal lens for this format is 105 mm, but I had a very nice Schneider Xenar 135 and was able to adjust the rangefinder to work with the longer-than-normal lens.

When I was at Grimes Camera Repair, we got a bunch oc nice Sekosha #0 shutters dirt cheap, so I used one of those, with a rather crude home-made fStop scale.

I also added a hot shoe and a mount for a cable releas on a home-made bracket. The cable release is held by a crocodile clip, and can be operated with my left thumb when holding the camera normally.

It's shown with a Leitz zoom viewfinder in the shoe.

I own several rollfilm backs for this, both 2 1/4" x 2 3/4" (6 x 7) and 2 1/4" x 3 1/4" (6 x 9) formats.
