ALPA/LINHOF ROLL-FILM BACK 6X7/120 (56 X 72 MM) is the back I have.
I'm located in the Netherlands and bought it in 2009 to combine with my digital back.
Always take good care of my gear but off course there are some user marks, still the back looks fine and works flawless. Kind regards
which Alpa back is it? how old? how much use has it seen? where are you located? thanks
