There's a flea market every Sunday in the Promenade du Peyrou in Montpellier, France. One of the stands has all this amazing vintage photogaphy gear.
At the end of August 2025 Marie and I spent a weekend in Montpellier and visited the flea market, among a number of other places. There we found this stand that was selling this very cool vintage photography gear, including cameras that were over a hundred years old. If you're interested in this stuff then it's worth paying them a visit if you happen to visit this beautiful city.
