Hi guys. I'm curious what the opinion is. The Go Shooter in question has good stickers, good paint, and the white is good. All blue parts however are yellowed so that they look blue-ish green (except for under the flip panel on the chest, which is it's natural color still). The headmaster has a broken arm, and there's a small broken piece from the blue on the arm, on the other side of the wheel. He has all his parts, originals, not repros. So, what's a good price on him? What do you think he'd be worth?
