Found the button today so here are some pictures for you....





The blue has been repainted from behind at some point and the outer edge isn't quite right..... I don't know whats wrong with it, it looks like something has reacted with it in the past. This damage is only the small area shown in the last 2 pictures, the rest of the edge is fine.
Overall the button is in good condition- no cracks at all, the gold isn't as bright as I'd imagine it was once, but it's getting on a bit.
So, as I don't know for certain what they're worth, I am open to offers for it and will definately sell.
