Fox Collectors

Gents,

I have found the approximate numbers of production for B grades in 20 & 26 bore, but could someone tell me how many were made in 12 bore?

It's still considered a "G" regardless of who made it right?
I thought that anything of that nature, being a Fox, would be a lot of money for those (me NOT included) who can afford it.

I read that someone at the Vintagers was going to show the only G grade made. Is that the one that Savage made and had engraved in Germany?
How much would a monster like that run someone or at auction?
