Hazells Streamline Blue Star Release II 1938

In 1938, Hazells increasingly came under the influence of Grays of Cambridge. Although the formal acquisition would not be completed until 1941, collaboration between the two manufacturers had already begun. As a result, Grays' design philosophy gradually began to shape the Streamline series. The Blue Star model underwent subtle modifications in form and finish as part of this evolving partnership.
