I have a Rodenstock 210mm f5.6 Macro-Sironar N mounted in a Copal 3 shutter. The serial # is 10690214. It also has 8x10 coverage. As shown in the photo's it is extremely clean cosmetically and was used very little. The Optics are clean, scratch free with no fog, fungus, or separation. Mechanically it works fine with accurate shutter speeds and a smooth working aperture. Price is $650 +shipping. For your peace of mind, you can check my ebay user id on Ebay which is "fotoworks", where my feedback is 465 at 100%.
