The British Library The British Library Thorens 'Excelda' portable gramophone: winding hole for the clockwork motor 21XFROWX1988-0003 21 Frow 1988 This is the winding hole for the clockwork motor and the winding key. The clockwork motor inside the unit would, when full wound, drive the turntable for just over the length of a single 10-inch record side. The Thorens 'Excelda' was one of the last and most successful of the 'folding camera' gramophones, being introduced at the beginning of 1931 and remaining in production until the mid-1940s. The tone arm, winding handle and diaphragm were stowed inside the instrument and assembled for use. The Excelda could play a 10-inch disc but it was necessary to clamp the record to its tiny turntable. The chances of losing the clamping nut, however, were minimised by its being used also to secure the cover of the instrument. The Excelda was a well designed, reliable machine and, in addition to the brown 1932 model shown here, was available in a range of crackle finishes including black, green and red.
