Although I am new to British rifles, I have collected and shot British SXS's for many years. I am framiliar with proof marks, engraving styles, etc.
This gun carries appropriate british proof (& view) marks on the barrel, action and bolt.
The barrel inscription "Westley Richards & Co. London" is in the appropriate location (spelled correctly) and is engraved rather than stamped.
The engraving, although somewhat sparce, and not appropriate for a "best Gun" seems quite tastefull and of appropriate quallity for a hunting gun. I have seen big name Brit rifles with far less engraving.
The scope mounts did originally raise a question in my mind, that's why I asked. I don't think hex screws were even available when this gun was made.
The serial number is appropriate for the era, and does kick out a year of manufacture on the WR website.
Do any of you know if there should be any other markings under the wood? What should I look for and where?
