Don’t leave your son a broken gun. That, is not a heritage. I know people who have left sons and daughters perfectly good guns with the knowledge that those kids have absolutely zero interest in hunting and shooting, which, is also not a heritage, but, that is a conversation for a different day.
Most guns cost you more than they are worth. Such is the nature of retail, be it guns, cars, groceries, et al. My father was a career Marine, and very sternly warned me that no gun should ever be left broken or nonoperational, his feeling was fix it or destroy it, now. I would prefer it go to an outfit like Numrich, to be used for parts, but, it is still technically being destroyed.
I guess I take the “in for a penny, in for a pound” approach with decent old guns. You might feel different.
Best of luck, at any rate.
