I grabbed a perfect, mint Zorki from eBay. Seller said 'Perfect working condition'. It was a mess, after two shots without film, it froze, couldn't change film speeds. Sent it to 'Oleg' in the Ukraine for a CLA. Came back smooth as! Such a joy to use. The whole exercise wasn't cheap but I love the camera, can't wait to throw some B&W into it. Used both a Jupiter 8 and Industar 61/D for these shots.
