1977 Queen's Silver Jubilee Trimphone Prototype

Silver Jubilee Edition Prototype. Produced in the UK by STC in 1977. Never issued to the UK public. Approximately 50 were made.

The Post Office were looking to issue a commemorative telephone to celebrate the Queens Silver Jubilee in 1977 and manufacturers were asked to submit ideas. STC’s offerings consisted of a Push Button and a Dial Trimphone both with a white body and blue handset with a gold insignia embossed into the back of it. The Push Button version also had blue keypad buttons. Unfortunately the Post Office rejected STC’s submission in favour of the Navy Blue Compact Telephone, but there are a handful of the STC prototypes in the hands of collectors.

This Trimphone was found in 2017 at a flea market in Ontario, Canada.
