Skybirds was a brand name for a series of 1:72 scale wood and metal aircraft model kits produced during the 1930s and 1940s, manufactured by the A. J. Holladay & Co.
These kits were designed by pilot and aviation journalist James Hay Stevens and comprised shaped wooden blanks with cast metal detail parts.
Photographs of aircraft models built could be submitted into competitions, in order to be displayed within the windows of the Hamleys toyshop in London.

It is possible that model making popularised the Supermarine Spitfire, despite it being statistically out-performed and out-numbered throughout the conflict by the, then, more-successful Hawker Hurricane.
