I have a great story on the subject. A good friend of mine saved and worked to earn a 20 gauge when he was a boy. I forget the make and model. Anyway, he was working a gun show a couple years ago and comes across a shotgun like he had as a boy. He asked the owner if he could remove the buttplate. Inside he found a piece of paper with his name on it that he put there many years ago. Charley is in his mid 70s, so the gun would be over 60 years old. Needless to say, Charley bought the gun.
