From left : Machine Wars Optimus Prime (MISB), Action Masters Optimus Prime (loose)
Machine Wars Optimus Prime (US version) has the same mold as its European counterpart (Thunderclash). Only the colors differ and the latter was supposingly the original mold to be produced.
I've been hunting for the Action Masters OP since I first laid eyes on it on Ebay :p but a MISB-condition costs a bomb, hence had to settle for a loose, complete one instead (for only a fraction of a MISB one, of course)...
Now, hunting for Thunderclash...heheh...
