It mentions that they were from a line called Mecha Warrior, and released in red and blue (hasbro did blue, yellow and white).
I couldn't find anything online about that line though... so info on when and how they were released is still a mystery.
Even the tfwiki has no info on them, and that's usually a good place to start.
Other dedicated pre-TFs sites had nothing as well. And since it is so long ago, it's unlikely anyone at Hasbro would know anymore.
Thanks Griffin, interesting thats theres not much out there but not surprising. Will keep looking and see if I can dig anything up.
