Cravens

Cravens Railway Carriage and Wagon Company Limited was a railway rolling stock builder in the Darnall district of Sheffield, England. Founded by brothers named Craven and known as Craven Brothers, later Cravens Limited, it remained a family business until John Brown & Company acquired a controlling shareholding in 1919. Its name was changed back to Cravens Limited in 1954 when it finally became a wholly owned subsidiary of John Brown. Provided by Wikipedia
