Nikon Historical Society-- hosted by the founding member Bob Rotoloni and members of the society. The NHS, based the US, has a worldwide membership. Our "Nikon Journal," published four times a year, concentrates on the history of Japanese photo equipment from the perspective of the Nikon Camera Company. The Nikon Journal often includes Nikon information not published anywhere else in the world. This forum provides an opportunity for conversation between collectors and users of classic film Nikons. See forum “stickies” for more information about the Society. If you are a serious Nikon Collector, you MUST be a NHS member. Join at http://www.nikonhistoricalsociety.com/!
That was my first guess too but now I'm not so sure. The focusing wheel part of the front plate is raised on the S (adjacent to the rangefinder window). On the photo, it looks like the front plate is flat. The camera may be something else.
