I’ve been too busy to keep this more up to date, but I can report another ebay purchase. The Envoy wide-angle. Made around 1950 it’s a 6x9cm camera with a 64mm lens. I shot four rolls before I noticed that the hole in the tripod bush went all the way through into the body. This is one of the shots that didn’t suffer too much from light leak. More too follow when I’ve fixed it up a bit.
