How Much does a Ted Williams shot gun cost?

Which one? Sears sold a lot of different guns with Ted's name on them from 1961 to sometime in the 1980's. A semi-automatic will bring a lot more than a bolt action or a pump. There should be a Sears model number (usually 3 digits, a period, and 1 or more additional digits) that can usually be cross-referenced to a manufacturer's model.
