But this bright red box near the former Mr Smiths is believed to be one of just five ‘K4 designs’ left in the country. Research suggests K4 boxes were produced between 1929 and 1935 which in Warrington would fit with the opening of the Ritz cinema and the remodelling of the landscape around it. The K4 was built to provide the services of a telephone kiosk and post office incorporating a stamp vending device and letter box and was one of only 50 produced. In 2010 the Chester Standard's sister title the Warrington Guardian reported the Letter Box Study Group, with members from across the country, visited the hybrid phonebox. And enthusiasts from across the world have also made it their mission to visit.
