HI guys

I bought this at a recent show, mainly because of the calibre

The serial numbers on the frame and barrel are the same, and the 3 blade leaf sight lead me to believe it was built like this and not a modified military rifle or shotgun

Posting on another forum I was advised not to shoot it despite a recent proof as RBs have a poor safety record????

The cartridge, a Westley Richards competitor to the .500 express but shorter, possibly for their "Improved Matini"
A favourite cartridge for India, I have a DR and "Improved Martini" in the same calibre

Extra safety on the hammer, to allow for ruptured primer?

Recent Birmingham proof marks for BP

Husqvarna trade mark?

Any ideas on the date?
