The third design of Dr. N.A. de Bruyne, the Ladybird was a single seat, shoulder wing monoplane, powered by a Scott Squirrel.
It was started in 1936 at Duxford by Aero Research Ltd as c/n DB.3 G-AFEG. It was not finished and taken over for competition by J.N.Maas in 1937 and redesignated de Bruyne-Maas Ladybird and given a new c/n, M.1.
It first flew at Cambridge in 1937 but was re-engined in 1938 with a Bristol Cherub. It apparently spent most of its time flying as DB.3/M1.
It survives somewhere in the Peterborough area.
