A rare Leica copy camera, the Melcon II. This rangefinder 35mm camera was manufactured and sold by Meguro Kogaku Kogyo, and was released in the summer of 1957. Its production and sales period lasted only about two years, with the total number made thought to be just a few hundred units. The original list price at the time was JPY 46,000.
Although it is categorized as a Leica copy, its appearance is closer to that of the Nikon S2 than to a Leica. For reference, the rangefinder base length is 60mm on the Nikon, while this camera features a longer 70mm base. Its styling is also reminiscent of another rare Leica copy released around the same period, the Tanack SD. The camera uses the Leica L mount, and is distinguished by its large viewfinder window.
It is equipped with a life-size bright-frame viewfinder without parallax correction, a lever wind, a hinged opening back door, and a body shape that is comfortable to grip. Overall, it is a thoughtfully designed camera that gets many of the essentials right.
The lens supplied is the well-regarded Nikkor-H 50mm f2. Rangefinder coupling is effective down to 1 meter, with closer distances handled by scale focusing.

Minor scuff marks can be seen on the bottom plate, but overall the body shows little sign of use and remains in clean condition.
All functions operate properly. The viewfinder is clear with no haze, though the contrast of the rangefinder patch is slightly weak.
The included Nikkor 50mm f2 lens should be considered a bonus item. There is coating deterioration on an inner lens element, and oil is visible on the aperture blades. Aperture operation and the helicoid function normally.
A Nikkor front cap is included.
Sold as is, without warranty.
