The Leica X-Ray camera was designed in the late 1930s to photograph fluorescent screens. Marked on the lens flange “W.X.” (Westinghouse X-Ray), some X-Ray cameras were converted from Leica Standards by Leitz New York. These “New York X-Ray” cameras have much variation in the parts supplied, since new parts were hard to come by during the war. New York X-Ray cameras use the full 24x36mm format rather than the Wetzlar version’s 24x24mm. A very rare Leica.
