The thermostat-controlled flue oven designed for this cooker marked the greatest single advance in gas cooker design since their introduction, and made cooking an exact science. The design of cookers has improved little since. This thermostat (called the 'Regulo' by the Radiation group of manufacturers) is of the expanding rod type. The cooker, which was made by Radiation Ltd of London NW10, was the finest of its time. Inscription on oven door: NEW WORLD/RADIATION LTD. 3/4 view.
