Does anyone know about the Winchester 59, made in 1959? I am researching this gun that wants to know the value of this gun. All I was told is as followed. It is a Winchester 59, and has a fiberglass cover barrel (so it doesn't rust??), and I think it is a 12 gauge. This is all I know. The owner says he thinks it was only made in 1959, and he is the original owner that bought it in 1960. Any info would help. Thanks..
