Leitz's right-angle VIOOH viewfinder. Black/chrome. It was produced for a long time from around 1938 to 1964.
It has frame switching for 35/50/85/90/135mm focal lengths. As you change the focal length while looking through it, the frame narrows in a very cyber and cool manner. Parallax correction is marked in meters.
There are small hand-engraved characters under the shoe mount. Although there are minor scuffs on the eyepiece and the front end, the black painted parts have little paint loss, giving it a rather clean appearance.
The viewfinder image shows some fogging and appears slightly white, but it does not affect practical use. Cleaning can be arranged for an additional fee if desired. The operation is smooth.
