Ministry specification 46/22 given the service name "Vanellus" when taken on for evaluation by the RAF against the Supermarine Seagull design. Operational history The last Viking amphibians were built during 1923, but the name was re-used for the twin-engine VC.1 Viking airliner some 22 years later, which saw service as the Valetta with the RAF and other air arms. Some Viking amphibians were built by Canadian Vickers Limited, a subsidiary company in Montreal with no previous aircraft manufacturing experience. Their involvement with the Viking led to a future line of indigenous flying boats beginning with the Canadian Vickers Vedette. No Vikings survive today although a full-size replica built for the film The People That Time Forgot (1977) is displayed at Brooklands Museum in Surrey.
