I know firsthand what a .410 double can mean to a boy. My grandfather had a wealthy friend who owned a plantation adjoining grandaddy's land. When I was 8 yrs. old he took me to his weekend home and handed me a J C Higgins, Tenite stocked, .410. Most beautiful figure in those stocks I'd ever seen.
He told me I could keep it as long as I kept it cleaned and oiled which I did. He would stop by occasionally and tell me to run get "my" gun, for him to inspect. About 4 yrs. later he did that, and as I handed it to him he said he was taking it back to give to his grandson. I was heartbroken, until he pulled a 20 ga. Rem. Model 11 out of the back seat of his Chrysler Imperial, and handed it to me.
Good on you for dedicating that gun to him, Victor. But, I hope it's a long, long time before it becomes his to own.
