Remington 1100 12ga.
Purchased by my Great-Grandfather in the 70's, given to my grandfather upon the death of my great-grandfather, given to me by my grandfather before he passed away. It was used to take all kinds of game through the Appalachian Mountains. I used it this past September to take 5 doves on opening day and use it to regularly to shoot skeep and trap.
It's only worth about $400, but in terms of family history and tradition, it's priceless.
