Your rifle was made by Winchester for Sears Roebuck- it is the Winchester 94. Sears sold firearms under their own brand names, such as JC Higgins. Ted Williams, baseball player, permitted his name to be used as a brand on Sears sporting goods. The Sears branded firearms are typically valued at about 20% less than the original brand guns. They are still a very good buy for the money.
