Widelux F6. The widening is smooth and the turret moves smoothly on 1/125 and 1/250. To my ear, it seems accurate. I have not tested it with film. The view through the viewfinder is mostly clear. The 1/15 speed seems to be fine but sometimes it seems to slip and fire at the same speed as 1/125 so I think this will require a service. Best to use it for parts for other Widelux camera repairs maybe. Selling as-is as Junk, No returns.
