Yeah, the G2 Trailer was all black and the resources section here shows it being released in 1993, although it could have a copyright of 1992 for when it was made prior to being released. Not sure why someone would go to the trouble of swapping out the underneath parts of the trailer. Looking inside, there are no number marking of "5" or "6" anywhere to be seen. Just a curious guess, but does anyone happen to have any of the reissue Primes loose? What is the Copyright on those? The only reason I ask is that the actual Prime that was paired with the trailer is a short stacks version.
I was wondering if it was perhaps one of the various reissues. Anyone have a loose one to verify by? The trailer is just in too good of shape with tight joints to be true vintage. And was there a "pepsi-cola" repro sticker that looked like this?
