I am on a mailing list devoted to old Canon SLR cameras. A while ago someone asked an off-topic question — how to use an old Gossen Lunasix light meter. I responded by publishing the instruction manual here.
Thanks to Google and the other search engines, there are hundreds of hits on my Lunasix page every month. Dozens of people have written to thank me — mostly from Canada, the USA, Australia or the UK. It warms my heart. From Venezuela, Leopoldo Diaz Rodriguez wrote:
