You are bidding on a very old Redfield Olympic sight. It looks like it should fit a Winchester and/or Remington rifle. It is marked Redfield Olympic Model. It was found in a very old dresser drawer. All dials turn and all functions operate/move and work as they should. The sight is fully functional. There is some very fine, I guess you would call it pepper rust here and there, but nothing too serious. More on the silver then the blue. I tried to show it in the photos. The peep/aperture is quite large, close to the size of a quarter. A great old sight!! With free shipping, no reserve and an opening bid of under $1, you can't go wrong!!!!
