I just purchased this SLR680 for a decent price but it has an issue. It seems to be missing what I think should be two screws on the left side of the plate (from the perspective of someone holding the camera with the lens pointed toward a subject) that connects the lens to the bellows apparatus. So the left side of the front cover swings kind of loose and isn’t secure. I tested with an empty film pack and the motor runs and flash works, but I’d love to get those parts secured. Does anyone know what kind of screws are supposed to go in those two holes or how those parts are supposed to attach. Happy to answer any questions that can help. Thanks!
