In reply to lewismansell:
Stanfords of London used to sell the TPC series (Tactical Pilotage Charts) of many remote areas. I think they are gradually being withdrawn from public sale (sensitive military information?) but I bought some for East Africa and for Azerbaijan which were excellent. In the latter case, our Russian and Azerbaijani hosts had never seen anything so detailed.
If you can go to the store, they'd help you out I'm sure. Otherwise, use their website, but I couldn't find a key to the map numbers on there. Maybe they are unavailable for the regions you want, but worth a try.
