The best years of Sunbeam were in their early history. They built up a tremendous reputation for quality and finish and this was to lead eventually to the downfall of the firm. By 1928 Sunbeam had become part of the ICI combine but did not add very much to group profits so in came the accountants and much of the tradition had to go. More parts were bought in and slowly some of the quality began to evaporate.
