This is a Japanese-made camera from 1951-1952. I am unable to determine for certain the model. To me, it appears to be an "Atom-Six-I" with a black lens standard. It is described as having taken 6x6cm exposures on 120 rollfilm. It has both an eye-level and a waist-level view finder bult into the top housing. It has an f-3.5, 75mm, Seriter Anastigmat lens, No. 7585. The "NKS" shutter has speeds of B thru 1/200. The aperture settings are 3.5 thru 22. This camera is being offered for parts only. Please review attached photos. 

REASON FOR SELLING: This camera is from my private 40+ year eclectic collection of "photographica." I sought out and collected anything and everything related to photography. Many antique/collectible cameras and photo related items are intended to be listed over the ensuing months as this extensive collection is made available to the eBay Community. There should be something for everyone, from the beginning enthusiast to the seriously advanced collector, as this huge accumulation includes items dating from 1843 through the 1950's. Listings will cover a broad spectrum of the photographic field: antique and classic still cameras (including miniature, novelty, field, studio, stereo, and panoramic), cine (movie) cameras and early projectors, images, books, magazines, catalogs, manuals, exposure devices, powder flash tins, foil-filled flash bulbs, early darkroom equipment, brass lenses, exposed glass negatives, assorted printing frames (including panoramic and stereo), novelty cameras, figurines, postage stamps, ribbons, medals, etc, etc. (A-82-28)
