Mine would be a 870 Wingmaster that my dad sold to buy me a trumpet while I was in HS in the early 80's. I had the serial number saved from the gun and found it about 15 years ago and purchased it back for him. I gave it back to him on what ended up being the last goose hunting trip we had together before he passed. It's a pretty common gun but one that I could never replace.
I've enjoyed reading the responses on this topic.
