He is a new owner of this M3 and I suspect, knowing where it came from, it might have not been used for years before he got it. I have linked a few photos showing the band.Maybe someone here can shed some light on this problem? band on photo 10-11-23scan010 (leica-users.org) <http://gallery.leica-users.org/v/Aram/misc/band+on+photo+10-11-23scan010.jpg.html> Line on negative drew (leica-users.org) <http://gallery.leica-users.org/v/Aram/misc/Line+on+negative+drew.jpg.html> -- Aram Langhans (Semi) Retired Science Teacher & Unemployed photographer ?The Human Genome Project has proved Darwin more right than Darwin himself would ever have dared dream.?
