It looks like when production moved to Thailand, they not only made new molds but they made more changes – the most obvious ones are the eyelid line on the windshield. Here’s some more.

Chick Hicks with headset has the eyelid line and an inset windshield.

2017 version.

Luigi & Guido with eyelid lines.

Jackson Storm has an eyelid line which gives the illusion of a raised windshield and the windshield is now inset versys just part of the body.

2017 Jackson.

Nigel Gearsley is a different kind of variant – the eye position & eyelid positions are different (no eyelid line).

2018 version with eyelid line, inset windshield and darker eyebrows.

2017 Sterling.

There might be more but I have not looked through everything but basically if you’re a complete completist … make more room.
