Leupold 30x40
1148 in 12 ga. auto, field grade, would probably sell for $200, if in very good condition. There is no such thing as a 270 gauge. It is a .270 Winchester caliber, in the 7400 Remington. In very good condition, it would likely $250 or so. The scope is usually a throw-in, and will only bring extra dollars if it is a Weaver, Redfield, Lyman, Leupold (unlikely). In that case...+$50 for a good weaver, $75 for a Redfield or Lyman, and $125 for a Leupold.
