Its possible its Knok.
However from my experience, my DD is in storage right now so can't actually go and confirm this, Knok's gray is much darker, as well as the blue face and chest being almost navy blue.
While Clouder has a very bright blue for the face and chest, and very light gray body just like this is coming across.
I question the engine being chromed? Neither partner has chrome on him as far as I know. However the Doubleclouder version does come with a chromed chest piece rather than the blue one Doubledealer has. http://www.tfu.info/1988/Cybertron/Doub ... louder.htm
Though I can admit it may be the flash playing tricks. Though isn't it much cooler to think you got a very rare Clouder he he
I... have the power!!!!
