Gaps in the maps

[dirk]

With the new map showing Saipan #80, got me to wonder about the other maps that exist;
1 thru 8 - Eastern Front; 9 thru 12 - Battle of the Bulge; 13 - Airborne; 14 thru 21 - Road to Berlin; 22 thru 25 - Elsenborn Ridge; 26 thru 33 - Fall of France; 34 & 35 - Kokoda Trail; 36 thru 39 - Kursk, South Flank; and maps 44 thru 49 - August 1914 (Infantry Attacks).
Maps 40 thru 41 Kursk, Northern Flank?
Wonder what kind of generic maps and what games they belong to from #50 to # 80(Siapan)?
