My Leica M3 is soon to get shipped off for a precautionary CLA (clean, lubricate, adjust) and a re-cover. IMO the new "vulcanite" will make it a 2019 next gen winner!
Dave, that's great!
If only I had kept my M3 double-stroke with dual range 50mm Summicron! It was exactly as old as I am, and I hope it's till around and being used. I sold it when I made the transition to digital photography and could kick myself for having done that.
Sometimes I use my only remaining 35mm camera, a nice Yashica Lynx 14e with great 50/1.4 lens.
