FSCarl Zeiss Jena Biogon 3.5cm f2.8

Here is a pre-war, uncoated Carl Zeiss Biogon formula 3.5cm f2.8 lens in Contax mount, will also work on the early Nikon S mount rangefinder cameras. The glass looks grea with no haze, fungus, separation or oil on blades. The serial number indicates this was made in 1938. It's one of the best pre-war examples you're likely to find. Serviced by the late and great Henry Scherer about 5-6 years back. Comes with both original caps as shown. I prefer F&F but regular paypal would be acceptable with 3% added. I'll pay standard shipping in USA. Return if not as described.
