Skybirds
Skybirds was the brand name of a series of 1:72 scale wood and metal aircraft model kits produced by A. J. Holladay & Co. in the United Kingdom during the 1930s and 1940s.
These kits were designed by James Hay Stevens and comprised shaped wooden blanks with cast metal detail parts. These were the first model aircraft kits in the world made to a constant scale of 1:72. This scale was later adopted by many other model manufacturers, such as Frog and Airfix.
