Harlan,
seems I have missed the French bashing part of the list

"Individual WWII Infantry with white flags and arms straight up"
I see plenty of selling opportunities here with different helmets : German (Stalingrad, Tunisia...), Soviet, ...Italian..., British (Tobruk, Singapore, ...; Bataan, Corregidor, Mac Arthur being not back yet), US (Schnee Eiffel, figs in greatcoats of course

),
Here I would love to see all the characters from the Great Escape, Steve Mac Queen on his bike included !
Not sure about what you mean by :
"Individual WWII North African Infantry
Individual WWII North African Heavy Weapons "
If this refers to figs in djellabas, they were not the bulk of the infantry and they wore the US helmet of WWI (not the British one).
More useful, and more representative would be figs in US battledress with Adrian helmets, . GHQ needs only two different masters for each individual inf. packs as you can mix these figs in Adrian helmets with the existing US infantry in the same units.
To these GHQ may add figs in berets (commandos, FFL), figs in US battledress with British helmet.
Also : about Germany in the 60's : more versions of the Hotchkiss Spz.
Cheers,
