Thanks for the list link I'll have to look for some of those. Som Berthiot has got to be quite a find.
Most pre contax II camera's I run into are plagued with rotted shutter ribbons 60 70 years to rot once replaced the cameras work fine. The post war iia/iiia don't use these ribbons most work the slower speeds stick only becuase the oil is dried and old once the camera has a basic cleaning all will be in working order again most likely work for another 50 years
