I just bought a Remington bolt action rifle. It is marked 513 on the barrel. I have determined it is probably a "S" sporter. It doesn't have the target stock or sights. The stock is checkered walnut, barrel is medium weight, and the rear sight is a ramp. Date code puts it Jan. 1947. My main question is that it is stamped "Scoremaster" not "Targetmaster". Is this correct for the Sporter model? The rifle belonged to a gun shop owner who is retiring and he believes the weapon to be all original. It is in, conservatively, 98% condition. No marks on the stock, no wear on the bluing, no buggered screws and not D&T'd. Absolutely one of the best looking older rimfires I've ever seen. Thanks everyone in advance for any help you might offer.
