GT; I have thought about this too. Havn't specifically gotten anything from my dad (like guns), but he is a great guy. I got a Arisaka from my moms dad although he didn't bring it back, and a Model 95 that was my grandfather Tinkers; that has a neat story with it.
I've told my son that most of my collection will be sold before i go, but there are certain items that he will get (unless something happens and I'm outofhere unexpectadly

)
That said, I have an excel document that lists everything and why I have it (from whom or if it is a family item).
