Originally a specialist manufacturer of mirrors, like many other companies, Attewell joined the war effort and in 1942 directed its engineering resources into making parts for the Spitfire aircraft, and so Attewell’s involvement with the aerospace industry was born. Formally registered in 1962, we have a long and successful history and we remain very proud of our heritage.
