Not passed down yet but....
My father is still alive and has, among others, a few choice, actual WWII-manufactured German weapons. He's got a Luger P08 with both (!) matching mags, a P-38, a gorgeous K98k and an honest-to-goodness PPK. They're all original, numbers-matching, properly marked, proofed, dated during the war, have the Waffenampt 359, etc, etc. He's also got a nice, WWII-made and very intact MI Carbine in the safe. He has no interest in shooting them, either. He justs takes them out of the safe every now and then for a fondling.
I'm the only one in the family other than him who cares for any off this stuff so, almost every time we spoke, he told me what I'm getting when he dies. He'd mention those above, his coin collection, tons of WWII memorabilia, etc, etc, etc. It got to be a little morbid. I had to tell him that it sounded like he was trying to make his passing sound appealing to me so now he only tells me that about once a month or so.
PS He's in good health, btw, in case anyone's wondering. There are no pressing health issues which would inspire death talk, it's just his way. He's a bit of a character.
PPS An odd thing, he never owned a gun until I got into them. He was always a WWII nut because it dominated his childhood but no guns. When I started seriously shooting, he took an interest in some real hardware. Despite the late start, he caught up in a big way. All of his guns were fairly recently purchased so he really dumped some cash into it.
