Model 1905 / Design E
Based on a 1905 model

The K.T.A.S company (Kjobenhavns Telefon Aktieselskab) bought in Ericsson's Model AC300 in 1904, which was a steel-cased magneto desk phone.

The K.T.A.S. model is notable for its red ringer cut-out button fitted on top of the casing.  Pressing this button would have cut off the bells when calling the exchange using the hand generator.  This feature seems only to have been used in Denmark.

In 1908 this telephone was supplemented by the little desk phone generally known as the D08.

Expoga removed the side casings to expose the generator, added a dial and gold transfers.  The generator and red button are now redundant.
