The 'problem' for me, is that they didn't see any value in old stuff as I do today.
I remember as a kid that my father tossed an old muzzle loader into a fire. A 300 year old school bench was cut in half and used outdoors until it fell apart. And cabin that dates back to late 1600's where modernized with electricity from a wind turbine and walls cut for large windows.. the story goes on. So very little was passed down to me.
My favorite inherited item is a beaten up Krag J�¸rgensen full of home made repairs. Both my grandfather and father shot incredible amounts of moose with it, not for fun of it, but the meat it provided the family.
When it comes to my collection of firearms, they are all registered and my daughter would have need a license to inherit them. So I'm 99% sure of that non of them will be handled down. They will be sold or deactivated/melted

But I try to keep other items for the future generations. Like a restored sailboat, two motorcycles and a car + some old stuff stacked away here and there.
..and almost forgot, I scanned all of my dias so that they will have them digitally and in a regular album
