V1? Those toys are like ten years old, I don't think you'll find any pristine pearly white parts anywhere, not even if you asked Yamato.
OT: My god, TEN YEARS. I remember the exact day in Shinjuku when those things came out, I was there in Sakuraya with another Macross Worlder called Matt, and maybe one other guy, just watching them roll out the new valks from the back room.
I also remember buying one and taking it back immediately because the plastic in the neck joint was glued wrong and would not move, it looked like it was welded together in a mess of white mush. The guy at the cashier pulled another from under the counter and handed it to me, no questions asked. These were certainly the "hey, it's Yamato, what can you do" days.
