Brook Steel and File Works
1868 Joseph Bennett Howell founded the Brook Steel and File Works, Sheffield.
Later established a separate department for the manufacture of steel tubes, and in conjunction with his son, Mr. S. Earnshaw Howell, established the Sheffield Tube Works at Wincobank, near Sheffield.
The tube works were subsequently amalgamated with the Brook Steel and File Works, as a private company.
