[Graham Boak]

"Boy" Bouchier, when commanding 54 Sq in 1936, was tasked with submitting suggestions to attacking German bombers, and came up with six suggested attacks. Somewhat to his surprise these were simply reprinted and issued. I have always assumed these were the ones still in use at the outbreak of war - he makes no further reference to them! - and not what you are looking for. However, 54 still had Gladiators at the time, as did other units, so presumably pilots in these types did train using Bouchier's ideas after 1936.

See his biography "Spitfire over Japan", p177, with all of three paragraphs.
