Hello Poppo.
Help me out here bud, exactly what is a wrong face??? Im not sure any of the folks who partook in WW2 could correct their faces per se as I do believe, good bad or indifferent we are born with our faces as they are

I do believe I know what you are mean perhaps arent satisfied with the sculpting yes? Many collectors have levelled the same criticism.
My thoughts:
Ancient world- Aeroart, though Im thinking if we are bringing the price down, gotta go with FL on Rome, East of India, even though they arent in business (i hear, i dont actually know), I think they did the best Greeks and KC seems to be the only game around for Egyptians. East of India did Persians.
Medieval world- I gotta go with FL Crusaders range.
British military history- gotta go Britains, just too much heritage, Zulu war, War along the nile, etc.
AWI- Pound for pound I think Britains has really pulled ahead slightly over KC and FL
ACW- Seems like FL is the frontrunner here by a nose though Collectors Showcase seems to be closing the gap. Britains also has a rabid ACW fan base too
Napoleonic- Dealers choice{sm4}
American West- Either KC or Blackhawk. They did a really nice Custer range. KC's are quite colorful and exciting poses
WW1- Still give the nod to Britains- again, a corporate heritage thing there
WW2- KC, That's their bread and butter. I still think TG has some exciting offerings though
Orient- KC's SOHK line is simply superb and the colors are truly awe inspiring. Their IC collection is first rate as well.
My two cents- for what its worth
Hey Lancer- any thoughts on Heco for WW1???? {sm4}{sm4}
