IMO the best choice is a Sicily + Malta map. The historical value of such a map would be huge, a war front from June 1940 to July 1943 with many possible uses. Here you can see the current status of the map and a selection of its airfields. Some are partiallly working already but a lot is still to be done...
Chinisia S.Giuseppe airfield (Borizzo in allied docs)
Catania Fontanarossa*
*note the wrong identification, as Gerbini was some kilometers to the west...
Castelvetrano
Trapani Milo
