T = Telephone Kiosk 4

The TK4—sometimes nicknamed the Vermillion Giant—was a design based on Giles Gilbert Scott’s TK3 but also incorporating a GR-ciphered letter box and two stamp vending machines in its rear side. 50 were made in 1927. In practice they proved difficult to site, with access needed all around the box and the mechanical noise of the svm’s in use disturbed telephone users.
