Ahh, so compatibility? 28mm? 32mm?
Sets with turbans, sets with slouch hats and sets with (of course)pith helmets. Maybe top hats too? And german pointy Hunn helmets?
So maybe 5 heads on a sprue, 1 with a bionic eye, 2 open face and 2 with gas masks? Or 5 the same on a sprue? Or what? Ideas please.
