Very nice story, Danny! It sounds like your grandfather caused quite a panick! It's ashame how things go when a family member passes. There's been quite a few instances in my family such as you describe. Some have caused family members to not talk for years because so and so wanted this. Even to the point of family sneaking items out of the house of the person who passed.
Your story also goes to show that typical items that you may see at a show or yard sale, you might pass on, but at one point could have been invaluable to someone else.
