As a point of total trivia , some might remember the six wonderful Inpact 1/48th scale kits of Edwardian Aircraft produced in the mid 1960's. ( Bleriot , Box Kite, Deperdussin, Antoinette and Avro Bi and Triplanes IIRC )
There were going to be three more -one of which was to have been the Valkyrie
I don't think it ever appeared.
