999 was the world's first number for automatically telephoning the emergency services. It was introduced in London in 1936 following a disaster in 1935 in which five women died in a fire in Wimpole Street while a neighbour was unable to contact the telephone exchange which was jammed with calls. The General Post Office which ran the telephone network at the time suggested that an easy to remember three digit number, which could be easily located in the dark or in smoke, be introduced which would cause a light to flash at the exchange alerting the operators to the urgency of the call. The number 111 was rejected as it could be accidentally dialled by knocking the receiver - telephones at the time were pulse dialled - 000 could not be used as the first 0 would make it impossible to prioritise and so 999 was adopted. One year after 999 calls were introduced in London they were introduced into Glasgow.

Detecting set L4A1 was the British Army designation for the Plessey P6/2 Metal detector range.
The P6/2 equipment consisted of a waterproof electronic unit and a set of operator-interchangeable waterproof probes. The operating mode was pulsed induction. Target detection was indicated audibly by a loudspeaker or plug-in earphone(s). Switched sensitivity and response times were provided. Power was supplied from internal batteries or an external source via an adaptor. An in-built battery check was provided. The function switch, loudspeaker, probe and earphone sockets wee located on a control panel at-the top of the electronic unit. The electronic unit was carried in a slung webbing haversack for manpack operation.
Four types of probe were provided as standard, each for a specific purpose. A connection cable terminated in a quick release plug is integral with each probe.
- P6A/2 was a tubular ferrite probe suitable for searches in bushes, streams and rugged urban and rural environments.
- P6E/2 Open Loop Probe was a lightweight probe, for ground search applications.
- P6F/2 was a short robust probe for general searches in restricted environments.
- P6G/2 was a light easy-to-use probe designed for the searching of persons.
Plessey could also supply special probes that could be designed for particular applications e.g. the P6C/2 sledge probe.
The P6/2 equipment was designed to perform over the frequency range 50 to 500MHz. When fitted with a P6A/2 or P6F/2 probe and an MDA7/2 earpiece the P6/2 was capable of operating within four metres of a 1W, handheld radio transmitter or within six metres of a vehicle-mounted 10W radio transmitter without malfunctioning, blocking, or causing interference to the receiver in the radio station.
Typical detection range for the P6E/2 Probe was approximately 220mm with a 2p coin or 250mm2 copper, 18 G and approximately 400mm with a pistol
