The Superb takes 120. I saw one for sale at B&H recently, but it had a Skopar instead of a Heliar. The Superb is the first parallax correcting TLR. The whole mirror/screen/viewing lens assembly tilts as you focus. It also has a bubble level in the finder, and the shutter speed, focus distance, and aperture are all visible from the top of the camera. Film winds horizontally by a ratcheting lever, and there is a frame counter, but no auto-stop mechanism.
Very cool. Those are all beautiful cameras & I'm sure are a complete joy to use.
