Tony,
Someday when your son is your age with children, he will appreciate the gun and the sentiments you felt as you restored it. If it were me, I would print the above and tuck it away with the gun so that when he grows up to use it, he will have not only have an appreciation of how you felt about him but he will also know that more than a little bit of you went into the gun as a labor of love for him.
