I keep them with all of the stuff that came with the gun. When selling or trading down the line. It will bring more money, and it show to the seller that the person may have actualy gave a hoot about taking care of the gun. I still have the original box my Savage Mod 12 came in.
Heck I keep stuff. I still have the original owners manual for my 92 Mazda truck in the glove box, with all recipts for parts and maintnance in it.
