Kiosk No. 6 - the K6 - was
introduced in the UK in 1936 (Mark 2 was introduced in 1937) to commemorate the Silver Jubilee of the coronation of King
George V. The 'Jubilee Kiosk', as it became known, was once again
designed by Sir Giles Gilbert Scott and was similar in appearance to Kiosk No.
2, the main difference being that the vertical bars in the windows
and door were spaced further apart to improve visibility. The K2 had not
penetrated far outside London, but the 'Jubilee' model became the first
genuinely standard kiosk and was installed all over the country.
Under the "Jubilee Concession", introduced as part of that year's celebrations, kiosks were to be provided in every town or village with a post office, regardless of cost. As a result of this scheme over 8,000 new kiosks were installed, adding impetus to the spread of the K6.
In the following year, the "Tercentenary Concession" was introduced: if a local authority committed to paying £4 a year, then the normal subscription, for five years then the Post Office would install a kiosk on request almost anywhere. This scheme remained in force until 1949 and led to almost another 1,000 K6s being introduced. The "Rural Allocation Scheme" was introduced to replace it: kiosks were allocated to rural areas and installed where recommended by a rural local authority, whether likely to prove profitable or not.
The K6 was the most prolific kiosk in the UK and it's growth was:-
The 'Jubilee Kiosk' is perhaps the best remembered example of Gilbert Scott's work (with the possible exception of Liverpool Cathedral) and is to this day fondly regarded as a typical British landmark. K6s survived the introduction of Nos. 7 and 8, but during the 1980s and early 1990s were frequently replaced with the modern KX 100 - 400 series of payphone booths. Thousands of old K6 kiosks were sold off at public auctions. Some were scrapped, but many more were put to a variety of imaginative and bizarre uses in private hands. However, the Department of the Environment and English Heritage worked with BT to identify kiosks, including more than 1,000 K6s, worthy of listing as being of special architectural and historical interest, mainly near existing listed buildings or in attractive town and country locations.
The Mark 2 differed in respects to the window frames being retained by studs instead of screws, two knock outs in the rear panel and four tapped studs on the rear panel for fixing the mechanism (theft prevention).
