As I recall from my Jackdaw wallet file on the Battle of Britain (familiar to a certain age group?) there was a map of the UK marked up with airfields & group/ sector boundaries similar to the one which the WAAFs used on the plotting table. There were little symbols for all the squadrons, RAF & Luftwaffe, which you could position at the appropriate airfields & the sole Gladiator Sqn was at Roborough, Plymouth - 267? Didn't seem like much to defend such an important Naval dockyard.
Perhaps something similar might prove educational for the youth of today?
