Condition of Leica gear is important. My M3 came to me over 35 years ago from its original buyer and with the receipt from Germany. He bought two M3 cameras from the factory while he was in Germany, and "my M3" was his back-up M3 that he exercised without film twice a year or so, I recall. The matching Rigid Summicron was also in LN condition when I got it. There were several accessories all wrapped in old paper. It was like a treasure find. I never let go of my M3 outfit. It is single-stroke with SN 990,xxx. There is a Brightline 35mm finder in its box. Why would anyone sell a Leica M3!
