if it will work, im also will prefer flying on the big map
anyway, two possible examples of 'historical' maps:
Dover-Calais
Isle of Wight - Cherbourg
the maps are small (the shown mapgrids are 50kmx50km !). But attack on channel ships, costal Airfields and Radarstations are possible with these maps.
In total, the given planeset (beside the Spitfire
) would well fit in a Greece Spring 1941 map. But i guess, that is too much work !
