Several years ago I received as a gift a .270 winchester Model 70 Ranger from a family friend, who has since deceased. It was basically a "hand-me-down," so I do not have any documention, etc., associated with the rifle. I plan on taking it as a second rifle on my trip to South Africa. Is there any thing special I need to do regarding the permit, etc. since this gun was not purchased by me? My primary rifle is a .300 winmag browning x-bolt special hunter, which I purchased myself and have all of the information on. Thanks in advance for your input.
