Additional Information

Another ill-fated attempt to give the Trimphone another lease of life came when some bright spark had the idea of cladding the telephones in leather.  The cases discoloured rapidly from finger grease and other contaminations but this did not deter the Post Office from including these unfortunate instruments in their Special Range in 1980 under the Deltaphone name.

Made by STC, the Deltaphone was just a leather covered Trimphone, with a Plug No. 505.  This plug was inserted into the jack socket and was then covered with a small sheaf, which was supposed to stop the plug being removed from the socket.
