A number of years ago, I inherited my step fathers Superposed Magnum 12. It's choked full and modified. This was a working gun, dragged thru the salt marshes on the Jersey coast and corn field goose pits on Maryland's eastern shore. Let's just say it has a lot of character. It still locks up tight and the top lever sits to the right of center. Just wondering the year it was made, Serial number 68xxx. Thanks all!
