Are you prepared to consider soft plastics? Because although it’s not my period, I have to say that the Zvezda box of ancient Greeks is one of the most beautiful things I have ever seen. Lots of the poses are dead ringers for the piccies in the relevant Osprey Elite. Quite rightly, the Plastic Soldier Review gave them a near-perfect score. The Zvezda Spaerans also look very fine, though I don’t have a box and so am going by the pictures. Again, they seem to have followed the Osprey quite closely.
All the best,
