The UK fansite "Spacebridge' has revealed some more unreleased Hasbro images, this time the Reissue Seekers (one has the Megatron gun) done fully chromed - Starscream, Thundercracker, Sunstorm, and an unknown silver one.

Scroll down the topic to see a couple extra pics of the Thundercracker.

It is being suggested that they were just produced as competition pieces (like the gold chrome Lucky Draw toys), but might have never been used, as no one seems to recall any competitions in the last 10 years for these.
