I was recently give a High Standard Nato Pintail 12ga pump. Serial #3082083. I checked the High Standard web site, apparently they no longer mfg shotguns, and have nothing in the way of archives. I did some interwebz searching, but didn't really find anything of use. I'd like to know the age and value...I've already got a 12ga Mossberg pump, and would like to sell this or trade for a 9mm handgun. I got it with a fancy leather case. Thanks in advance.
