Your comments:

• In 1949 when I was GPO apprentice at a training school in Penarth South Wales, part of our training was to dismantle the complete 121F telephone then reassemble and rewire it. It then had to be connected to a switchboard to prove than it worked, both outgoing and incoming. Also the dial had to be tested. The letter F denoted that the dial was a numbered one. Telephones with the letter L i.e. 121L denoted it was numbered and lettered for the London telephone network.
