Corgi is one of the historic car modeling brands. The Corgis, launched in 1956, were the first ever to feature windows, reproduced in transparent plastic. Corgi were a Mettoy brand, a company founded in 1933 by the German immigrant Philipp Ullmann, based in Northampton and then in Swansea (Wales). The Corgis were made of zamac, approximately 1:43 scale, and were soon equipped with many working parts such as opening doors and bonnets or suspensions. The vehicle models known in films and television series were particularly successful. In 1964 a further range of smaller models in approximately 1:66 scale was introduced. It was first called "Husky" and then renamed "Corgi Juniors" in 1970. In the 1970s many models in the main range were made in 1:36, but in the following decade Corgi again used 1:43 scale for cars and 1:50 for commercial vehicles, moving production to China. In 1999, Corgi took over the Lledo brand, also continuing production of the 1:43 Vanguards range.
