Pretty much the same here. My boys won't want mine but none of mine belonged to a family member so have no real sentimental value. I don't need longer range than the .303 and I've hit targets out past 300yds so I'm sure it's more than adequate for any hunting I might do in future. It just has a flip-up rear sight stamped 300 and 600 which I take to be yards as Britain wasn't doing metric in 1942. #1 son gets all my fishing tackle when I go and there is lots of my dad's and his dads stuff in there I should label so he knows what's what. He'll love the fly rod as I have all my life and take great joy in catching a nice trout in his great grandfather's name.
I think about the only gun I would like to get is a double barrelled shotgun. I had a Wingmaster 12G pump but had cut the barrel off and reduced the stock to a pistol grip. I called it "The Toy" and had it stashed at the family cabin for years but a rebuild was going to happen so went there on my 50th b-day and brought it home. Got pulled over by a cop for speeding on the way back who asked to search the car but I refused and he let it go. Never even gave me a ticket either. As soon as he left I had to change my skivvies tho.
Maybe what you have has some value to collectors and you could get some decent coin for them. If you should pass unexpectedly they would probably end up in the hands of the authorities and be destroyed and that's a crying shame.
In 50 years I doubt having any firearm at home won't be legal unless for sustenance hunters. Everyone else will have to rent a secure locker at a range and only be able to use it there. Here in Canada at least tho I'm sure Americans will hang on to the wild west mentality much longer than us.
