A universal viewfinder made by Nippon Kogaku. A copy of the Leitz VIDOM, with an upright image. Finished in black paint and chrome. It appeared around 1954 and is thought to be a model from the era of the Nikon S or early Nikon S2. Parallax correction is marked in feet.
It offers selectable framelines for 35, 50, 85, 105, and 135 mm. The nose is threaded to accommodate the 28 mm attachment.
The finishing is excellent, and its build quality strongly reflects the character of Nippon Kogaku.
There are scuffs and paint loss in various areas, but the overall exterior condition is generally good. All functions operate properly, and the view is clear.
A leather case is included.
