TK Armor is the maker of AM 1.0 and AM 2.0 here in the US, and TK Armour is a UK based guy. I own probably 15 of TK Armors helmets and 4 sets of armor. Deffinatly two different makers. mytkarmor.com is the US based guy very honestly, high gloss, thick pulls, and all comes pre trimmed, but his site is no longer up but you can find him on Facebook as TK Armor. The shelf is all AM helmets starting from left to right AM, AM 1.0, AM 1.0 conversion to Hero, AM 1.0 Shadowtrooper, AM 2.0, and on the right is the AM 3.0. AM 4.0 coming soon with one piece cap/ back instead of the two piece cap/back.
