To Know About Design and Repair of Russian Cameras. I purchased this hardcover book from a friend of the widow of Mr. Maizenberg not long after he passed away. She and her husband were selling about 70 copies which remained from the final printing for Mrs. M. This is the English language version, copyright 1996, 306 pages, excellent or like new condition. While it mainly is devoted to Russian cameras, he does a very good job of explaining several camera basics like rangefinders, shutters/shutter durations, beamsplitters, etc.
This is a terrific reference for any student of cameras, camera construction, repair or maintenance. $30 plus the cost of shipping.
PayPal ok for international, check/cash/money order for USA buyers please.
