I have seen several (about four in total!) of the chrome finish Russars. Two in Uk, of which one I bought, and the other at a camera dealer in New York. I believe that the owner is Russian and that he has a pipeline of optics and cameras coming in from the former USSR and its various states. If you nned the serial number and the condition, I would be more than glad to provide it to you. Mark Chaney figured that you would like to heard about this. Regards, Evan
