One call sign, 'MPB' on wooden plaque, probably made by Marconi's Wireless Telegraph Company Limited, Chelmsford, Essex, England, 1900-1950.
Marconi's Wireless Telegraph Company had the monopoly on the commercial side of wireless telegraphy from its early days, and eventually the Naval side as well. Every ship carrying Marconi equipment or officers had a call sign beginning with 'M'. Call signs are unique identifying codes for use over telegraphy and radio. In 1912, 'MPB' was the call sign of the 'Empress of Britain', a transatlantic liner that travelled between Britain and Canada.
