Just so you guys know, there's an assload of 21st's figures out there... I'll break down some of it off the top of my head...
-1st series WW2 Europe Infantry (non-removable helmets, though the heads can be used for customs if you're creative. Helmets come off but leave a gap/holes in the heads and they're misshapen. Some just need a little hair sculpting).
-2nd Series Vietnam... On the Nam figures, the Cong and NVA troops don't have removable headgear. The U.S. troops do have removable headgear. The Nam series isn't as easy to come by though, and some figures are flat out a pain to find. A Navy SEAL has a bandana, there's a number of others.
-3rd Series U.S. and German Paratroops... There's probably the most and best headsculpts in this series. A number of grimacing faces, but there's some fantastic neutral headsculpts for both sides. There's like 6 or 7 figures of both nationalities.
-4th Series Battle of the Bulge/Ardennes... Fewer headsculpts, but all are neutral.
-Sub-Series Pilots... They packaged pilots from the planes individually. The leather flight caps aren't removable though.
-Sub-Series Patton... General George Patton in 3 flavors with his pit bull terrier. Same head on all 3 figures.
-5th Series US Marines (Pacific Theater, repainted 3 times but no new heads).... Lots of headsculpts. Some more neutral than others. Some very neutral, some really exagerated. Lots of variety.
-6th Series Japanese Infantry... Again a mix of neutral, semi-neutral, and flat out exagerrated headsculpts. All Asian of course, which is positive for variety.
-7th Series Battle of the Bulge (Series 2)... They just started shipping. These are probably what you got BrentS as they're including interchangeable heads, torsoes... They're probably the best ever. I haven't picked them up yet and I so desperately want these figures in droves.
They have a U.S. Rifleman in trenchcoat, awesome.
Anyway, that's 21st's line-up... That also doesn't include NEW pilots like the Jet Fighter pilot, and some of the others. There's German and US drivers for different vehicles too... And that doesn't even get into what BBI puts out. From BBI SWAT (older though) onto BBI's foray into World War 2 figures. There's a lot of headsculpts available between these two companies.
Oh and I forgot Sahara figures too which I see more... Good civilian bodies/robes there.
There's more coming too... They're far from done.
