One way or the other, it was your call. It’s what I’d have done as well. Now, it were mine I would set down, with pencil and paper and write up a short history of your Grandfather, his hunting history, your hunting experiences with him, and how you received the rifle. I’d include a photograph or two of him, maybe one with you and him together. I would also explain why you had never shot it, so whoever ends up with it will know about you and the rifle. I would buy or make a nice leather envelope, put this written history inside it. With a leather lace, I’d tie it to the rifle and ask that it be kept with the rifle so future owners would know as much as possible about it’s time in your family. For an even extra pop to the history, print out this entire thread and put in the envelope too. Many years from now, some appraiser on the Antigue Road Show will go nuts over both the rifle and written history with it.
I know, I’m a weird Dude…….. but that is what I’d do, to add some extra satisfaction to future owners.
Now 53, I kinda think that you should wipe it down good, along with your Dad’s rifle and post a picture of those family heirlooms………. Just saying……..
