For sale is a really nice brass scope that would look great on a muzzle-loader or vintage cartridge rifle. The tube is 3/4" diameter and 32-1/2" long. The only markings on the scope are "4X15 Japan" on the eyepiece. What makes this scope especially interesting are the rings and bases. I have never seen anything like them. Three of the bases are stamped "Leupold" with a patent number. These same three have rounded bottoms for a round barrel or receiver. The other two have flat bottoms, one of which has a male dovetail. All these bases are adjustable for elevation while the rings are adjustable for windage. All in all, a very interesting set-up. Overall the scope is in very good condition with minor ticks and flecking. Screw-in brass lens covers included. PM me your email for additional photos. PRICE: $150.00 shipped for scope, rings and bases.
