thomas and friends mini series

The Wiki page states that there are 2 variations of Spencer Cyborg. I finally got one in a blind bag yesterday and now I know why. The Cyborg Spencer in the blind bag has black outlining his face and a gray on his sides. The Cyborb Spencer that comes in the box from the San Diego ComiCon has blue, like the blue Chillin' Skarloey is made of, outlining his face. He also has an almost chrome or mirrored look on his sides. So I guess there are two variations. The other variation I have is a knock off I'm pretty sure. Top is blind bag, middle is SDCC edition, and bottom is custom made I think.
