It is true that we lack variety in WW1. I am sure that whatever Strelets make for that era will sell well.
I agree that Early Serbians are a must. People were put of by the Coates & Shine set; mostly because it was uninspiring with dull poses and poorly sculpted.
Strelet's choices of WW1 subjects have been great so far. I particularly like the big-gun sets and the cavalry: looking forward to the Austrian Honved.
