Light Straw: Making clear sense of telecommunications history.
Light Straw was the paint colour choice for Strowger telephone exchange racks from about 1960 onwards, until the System X racks of the 1980s began to displace them.
Today, Light Straw (shortened to Lightstraw for convenience) is the adopted brand name for a range of web and book-based published histories of the General Post Office, and associated themes under the My GPO Family banner.
