In all my years of shooting I have never had to return a firearm to the mother ship until now. I keep mine and when I sell one the box goes with it. Keep them imo.
This. Object lesson: When I bought my 2nd Generation Colt SAA, in 1974, I threw away the box it came in, because the box was shopworn. Today, Stagecoach boxes like that are selling for hundreds of dollars, even if in poor condition. Someone was even making reproductions of the boxes, which themselves were selling for hundreds of dollars.Keep them or wish you did.
