Sebastian, maybe you could make the range a little wider: diorama/figures/armor/aicraft/ship/etc, and invite some guys and girls from Aeroscale, Historicus Forma, Shipwrights etc... to join. Not only the armor was black&white once - I've seen in TV evidence for B&W airplanes and ships as well

I've even seen spaceships that were B&W so Model Geek guys may be interested as well
