Title: The Silvertown Telegraph Works house flag.
Description: The house flag of the Silvertown Telegraph Works, a subsidiary of the India Rubber, Gutta Percha and Telegraph Works Company. The parent company was founded in 1852 by Samuel Winkworth Silver, who gave his name to the district on the north bank of the Thames. The company stopped making telegraph equipment around 1930, and eventually became part of BTR Industries (formerly the British Tyre and Rubber Company). This later merged with Siebe to become Invensys.
