The previous thread on the Purdey that's for sale, provoked a thought concerning an N. Guyot shotgun I own.

On the barrel flat there is one mark only, which is the London provisional proof. Any ideas on why the French N.Guyot would have the London proof mark, and also, why there are no other proof marks whatsoever on the barrel flats?

I presume that the barrels were sourced from a London firm, and would assume that the there should be other French proof marks before leaving the Guyot shop?

Thanks
