I just acquired a genuine Leica leather case to fit my Leica IIIf camera but the fixing screw inside the case is a smaller diameter than the screw thread in the bottom plate of the camera. In every other respect the case fits the camera perfectly. I read somewhere about there being European vs American (?) thread sizes. If so, does anyone know if there is a screw in adapter that can be used to reduce the size of the thread on the camera?
Thanks
