I have a Whitworth/Interarms chambered in 300 win mag. According to the date stamp it was made on Nov.'77. Sights and barrel band are soldered on, and has great wood. On the barrel it reads Whitworth Rifle Company Manchester, England.
It does have british proof marks on the barrel and reciever.
I had the 3pos safety installed.
