So I bought a Generations Thunderwing off eBay some weeks ago just because I was curious about the mold. It's decent, I like it, but I can't help but wonder if the plastic has "yellow'd" or not. The plastic is something of a noticeable tan color, but it's uniformly throughout. Can anybody else confirm if he's supposed to be this color or if the plastic has degraded?

It's not a dealbreaker on either answer, I'm just curious.
