Judging from the fact that the arm ramps are missing, I'm gonna guess it's a real Fort Max - maybe it was a spare that was badly yellowed and missing everything 'cept Cerebros so the owner decided to have it gold chromed. That's my guess, cos if it were a KO then why chrome the toy but not the ramps? I wonder how that thing looks in battleship and city modes. (well, pretty crap w/o the ramps)
