I have the original 4 digit serial number 10-22 rifle that I learned to shoot, and my son learned to shoot. It's totally original with all the pieces. I've been told there's too much value to keep using it. It wouldn't kill me to put it aside, as I have another and a charger also. Is a 1960's original 10-22 worth not taking out and shooting? Probably doesn't matter but serial # is 39XX
