This camera is an early model of the Mihama Six S, a 6x6 and semi-format coupled rangefinder spring camera manufactured and sold by Suruga Seiki Co., Ltd. in 1955. Switching between 6x6 and semi formats is done using a mask built into the film chamber, so there's no worry about losing the mask. By the way, Suruga Seiki Co., Ltd. was founded in Mihama Village, Kamo District (present-day Minami-Izu Town) in 1952, and its original company name was "Mihama Seiko Co., Ltd." However, the company changed its name to "Suruga Seiki Co., Ltd." in 1953 or 1954, and then to "Mihama Camera Co., Ltd." around 1956 or 1957. Most "Mihama" models were manufactured by Suruga Seiki. The early model of the Mihama Six S has "Mihama××6" embossed on the leather of the front cover, while the later model has the "MC" logo embossed, reflecting the change in company name. Also, the early model has the old company logo "MSK" engraved on the strap attachment part of the shutter unit, but this is omitted in the later model. The product functions well. The body has age-related scratches, dirt, dents, rust, peeling of the plating, and peeling of the leather, and the appearance is not very good. The distance ring position is shifted about 1mm to the right. The bellows are slightly distorted and have damage at the corners, but there appear to be no holes. The film guide rollers and guide rails are dirty. The pressure plate is generally in good condition. The film mask for the semi format has no particular problems. The viewfinder is quite cloudy, and the double image is barely visible. The shutter, Copal-MX, operates at all speeds: B, 1-1/300. The aperture and self-timer also work without problems. The lens is a C.KEPLER Anastigmat 75mm F3.5, and there is general haze due to coating deterioration. *Specifications Lens: C.KEPLER Anastigmat 75mm F3.5 Shutter: COPAL MX B 1-1/300 with self timer Focus: Coupled rangefinder, all-group focusing Viewfinder: Reverse Galilean type, 0.8x magnification Film advance: Red window type Dimensions: w: 139mm h: 107mm d: 48mm / 101mm *1 Weight: Approximately 800g Release year: 1955 Original price: 14,000 yen
