I don't remember the box and which brand it was, probably a Bandai, bought in 1987 on the marketplace. It was a 1/55 VF-1S and I immediately called it the chief mecha of my toy/army collection.
Later on I bought some kits of a Regult and a VF-1A brownie in Gerwalk position, built and painted it as good as I could and played with it. The regult lost it's legs soon and I used it as my last defender. I don't know the scaled of these kits, but they were pretty big, especially the Brownie Gerwalk.
All of these toys were lost when we moved to another home; my father gave them all away to the neighbourhood kids, but I didn't really complain. Guess those were the puberty years when the toys were discarded... Too bad...
In the early nineties, I don't remember exactly, I bought a Bandai reissue 1/55 VF-1S Super Valkyrie during my vacation in Turkey. I think I was still missing my ol' valk and wanted to replace it. This one was priced for about US$12.50!!!
It still stands here behind me on top of a bookshelf, some stickers aren't even applied yet but the projectiles are loose, the only one that is displayed because there is no other room for my other recently acquired Yamato's and poseables. I should clean up my place...
