British Telecom and the GPO leased and Rented this unit, which answered calls with a personally recorded message.
Unfortunately no callers message could be recorded. This unit is marked BT.

Your comments:

  • Apparatus were rented not leased, as the GPO retained ownership.

  • As BT did not come into existence until 1983 the unit was used by the General Post Office which in 1967 became Post Office Telephones.

  • I was a young Linesman sent to repair a bank of these at the Ministry of Agriculture. The unit had a length of tape, not on spools, just folded up inside. It used a single head with a tape having a thin transparent window near the end. The light from A small bulb would shine through onto a photo-cell when it reached the end of the tape.
    Unfortunately if the Bulb failed, the unit wound not stop

  • As a Linesman I came across these machines the first were valve operated and the later versions were transistor operated. We had a local weather Forecast provided by the met office at RAF St Mawgan it was recorded on a slighty elongated tape on a 1a, the tape used to get quite tatty with the heavy usage and had to be changed quite often the replacement tapes being made up locally.
