I recently sold my two M6's because as I get older I get more disabled and can't lug them around any more. I got quite emotional when I parted with them. I decided that I would at least like one leica to fondle from time to time and someone has offered me an M4 serial number 1230799. Seeing as I know absolutely nothing about how much a Leica is worth (mine went for much more than I expected) because I was a user rather than collector, does anyone here know anything about the expected price for an average condition one. It's chrome which I believe makes a difference. nod.
