Thank you Captain Pedantic. From the wiksters…
“The Gloster Aircraft Company was a British aircraft manufacturer from 1917 to 1963.
Founded as the Gloucestershire Aircraft Company Limited during the First World War, with the aircraft construction activities of H H Martyn & Co Ltd of Cheltenham, England it produced fighters during the war. It was renamed later as foreigners found ‘Gloucestershire' difficult to pronounce. It later became part of the Hawker Siddeley group and the Gloster name disappeared in 1963.”
Anyway I think it looks a bit Avro?
