I used to have two of them (one was Autobot HQ, the other for the Decepticons), but alas I haven't been able to find them at my parents' place (I suspect they've been chucked ). I did manage to take a photo of one of one of them in 1999; shortly after getting Big Convoy, I decided to recreate the scene from the Matrix Quest when Thunderwing blasts Powermaster Prime w/ the Tainted Matrix.
