I just a great laugh...."Excellent original condition" and Farquharson. It is neither. The gun is a nice period custom(80's gun I would guess) built on a Westley 1897 action, re-stocked, re-barreled and custom engraved, chambered in a cartridge developed long after that action ceased to be made. A nice rifle if you can get past the stock design. 7 Rem Mag is not really my thing in a vintage rifle.
Yeah, the calibre is not one i would like, being a british rifle, .303, .300H&H, or .375H&H would be better.
