hello, i have a Winchester model 12 12 guage shotgun. i looked up the serial # for a date, it is a 1958. regular models seem to be common, but mine breaks in the middle and goes into a carry case. havn't been able to find any info on it. just wondering if anyone had any idea of how common this shotgun is or a possible value. it was my grandfathers shotgun, so i wont be selling it. i just would like to know a little more about it.
