Here is a good example of the miniature gramophone produced by the Swiss Thorens Company in about 1931. These small gramophones were sometimes known as "Cameraphones" due to their likeness to folding cameras of the time.
This model is in good condition with an original "Exelda" sound-box and works really well for such a small machine. The inset picture shows the components stored away inside the all-metal case.
The knurled knob that holds the lid in place is also used to bolt down large records (up to 10" ) on the very small turntable. A lever inside the case at the back right controls the speed.
