I recently purchased a huge collection of cameras from a former employee of Kodak for almost 50 years. He said all the cameras worked great when he last used them in the 90s. So unfortunately none of them have been tested but appear to have all pieces and seem to have working mechanics. I don’t know a ton about them but will gladly answer any questions
