I completely agree with titrisol - the meters in these cameras usually are not killed by age... at least in my Vito CLR of the same age the meter works well within 1/2 stop. That's maybe because Gossen was an OEM manufacturer of the meters for Voigtlaender and Zeiss Ikon. Maybe the real problem is related to corroded wires or some passive elements (resistors) in circuitry, or the galvanometer wire is bent? Good luck with your repair, I love such type of cameras very much
