Founded as Tinsley, Steel, Iron and Wire Rope works in 1900. Known as Tinsley Wire from 1930, after a merger between 3 separate concerns. Now mainly modern buildings (Bayliss, 1995,30) although 'cities revealed' aerial photography indicates there may be some surviving earlier buildings within the complex as a whole. Detailed development of the surveyed enclosures visible on the first edition OS difficult to ascertain because there is no known enclosure award for Tinsley.
