About the collection at Avoncroft Museum
Avoncroft is a fascinating world of historic buildings covering seven centuries, rescued and rebuilt on a beautiful open-air site in the heart of the Worcestershire countryside.
The Museum also houses The National Telephone Kiosk Collection which was relaunched in April 2002 as part of the Connected Earth project. The collection explores the development of the telephone kiosk both in terms of social and material roles.
There are many major artefacts on display at the Avoncroft Museum. Some examples are shown below.

B1 standard building & Unit Automatic Exchange (1950s) : off the peg
This building was an actual working exchange that was moved lock, stock and barrel from its working location in Essex to the Avoncroft Museum for preservation.
It's a typical example of the type of exchange in use at the time. Buildings were constructed virtually off the peg. They came in different sizes and materials, wood, brick or stone, chosen to fit the location and budget. This B1 wooden construction replaced a smaller exchange, as demand increased in the area.
The Unit Automatic Exchange was created in a similar way. It came in different sizes according to the number of telephone users to be served - 200, 400, 600 etc. This example, the UAX 13, could have served a maximum of 800 connections.
Police call pillars : pillars of society
The telegraph and telephone meant that people could get in touch quickly, which was especially useful in an emergency.
The emergency services started to put telegraph alarm points and later special telephone boxes on the streets in urban centres, which gave both policemen and the general public a direct line to the police station.
The PA1 (left) was the standard police telephone pillar available in the 1930s which was later upgraded to the PA3 (right).
Avoncroft also has examples of larger police and roadside emergency boxes.
Different types of kiosk : collectible kiosks
Avoncroft has more types of British telephone boxes than anywhere else in the world. All the major models are on display, as are examples of most of the less well known designs.
For example, there is a K4. Nicknamed the 'Vermillion Giant', this combined the classic K2 kiosk with stamp machines and letter box to form a '24-hour post office'. It was not a success - the thing was too big to fit on most sites and the stamps became damp. Only 50 were ever made.
Rarer still is the K5 'flat pack' kiosk of 1934 - a transportable knock down design made in steel faced plywood for use at fairs and exhibitions, It's thought some were made - but if any survived, they're very well hidden. The one at Avoncroft is a modern reproduction, built precisely in accordance with the original drawings.
The K7 - Neville Conder's innovative design of the early 1960s - is also a spotter's delight. Just six prototypes were produced in aluminium, one of which lives on at Avoncroft.
Visitors can make and receive calls in most of our boxes. It's not just the kiosks that have been preseved, but the interiors too. This is very much a working museum.

The Strowger automatic switching system, designed to remove human intervention in connecting telephone calls, was invented by a US funeral parlour proprietor in 1889. It was adopted in 1922 as the standard for all automatic telephone exchanges in the UK. This electro-mechanical technology persisted for over 70 years, gradually being replaced by digital or modern electronic exchanges, until the last Strowger exchange in the UK was closed on 23 June 1995.
The standard Post Office prepayment coin collecting box consisted of a pressed steel case with stove enamelling as a protection against corrosion. The top portion houses the mechanism and the lower portion forms a cash compartment. On top of the box 3 coin slots are provided, which would initially have been marked "penny", "sixpence" and "shilling" prior to decimalisation.
This type of coinbox was introduced in 1958 at the same time as Subscriber Trunk Dialling and tariffs based on timed units/distance. It worked in conjunction with a coin and fee check relay set in the exchange. Money was inserted when the called customer answered the telephone or the credited time ran out.
One of the best-known manufacturers of telephone instruments, Ericsson designed the speakerphone for use in police call boxes. The patent for improvements in or relating to police, fire and ambulance telephone call systems was submitted by Ericsson in 1931 and accepted in 1932. The installation of the speakerphone meant that the public could access a direct line to the local police station, to report emergencies or to make routine enquiries.
The coinbox works by holding the coins in suspension in a container which is controlled by two press buttons, A and B. To make a call, the caller would press Button A, depositing the coins in the cash box and setting up the circuit for speech. If the call could not be connected for any reason, the caller would press Button B to retrieve the coins.
