I recently got a G1 Optimus Prime and inside the trailer it's got a gray spring-pusher (for Roller). I've seen some that have a black pusher too. My question is this... does the gray pusher mean it originally came with gray missiles? Consequently, did the black pusher variants always come with black missiles? I need to pick up some missiles for it, but I would like to make sure they're the right color for that variant.
