Really interesting post. I recently bought a new 2020 ATA helmet kit to match my full ATA kit from 2017. (The idea being to have both an ESB and ANH version of my TK). Built the new helmet kit ... very happy with it, love the quality and thickness of the ATA gear. But! After patting myself on the back and putting the new helmet next to the older kit. The ABS is clearly a different stock and the shade is different. 2017 plastic has a hint of cream / egg shell to it, and the newer stock is a clean ‘appliance’ kind of white. I really don’t want to paint either kit, so yeah got a new display helmet I guess. Maybe the newer helmet might ‘antique’ with exposure to sunlight or something. Anyway, I guess my point is it’s hard to get a great match even with the same maker.
