The Swansea and Mumbles Railway, located in South Wales, UK, was the venue for the world's first passenger horsecar railway service (1807)

In 1889, a new company, the Mumbles Railway & Pier Company, was incorporated to extend the railway beyond Oystermouth to a new pier close to Mumbles Head. 
The first section, to Southend, was opened in 1893 and the remainder, including the pier, in 1898.

The tureen shown was produced for and supplied to the British Government; it was ultimately property of the Crown/Government, hence the GR-VI cypher.

Dunn Bennett (and others) were given government contracts throughout the late 1930s and into the 1940s (WWII) and produced canteen ware - most likely for the armed services.

The ‘W’ within the diamond most likely relates to the products being commissioned and produced for the Office of Works (until 1939) and the Minister of Works (post 1940). This mark is there to distinguish the piece from being normal ‘utilitarian’ ware for public sale or belonging to anyone organisation.
