British K6 Red Telephone Box Original

K6 In 1935 the K6 (kiosk number six) was designed to commemorate the Silver Jubilee of King George V. It was consequently sometimes known as the "Jubilee" kiosk. It went into production in 1936. The K6 was the first red telephone kiosk to be extensively used outside London, and many thousands were deployed in virtually every town and city, replacing most of the existing kiosks and establishing thousands of new sites. In 1935 there had been 19,000 public telephones in the UK: by 1940, thanks to the K6, there were 35,000.

The design was again by Scott, and was essentially a smaller and more streamlined version of the K2

Size. The K6 was 8 feet 3 inches (2.51 m) tall and weighed 13.5 cwt (0.69 tonnes).

The paint colour used most widely today is known as "currant red" and is defined by a British Standard, BS381C-Red539. This slightly brighter red was introduced with the K8 model in 1968, but went on to be used across the estate on previous models too. Hence, for complete historical accuracy, any kiosks in pre-1968 settings should really be painted in the previous, and slightly darker, shade BS381C-Red538.
