I personally would not even keep it around, to easy for someone to make it functional, if it stays the frame cylinder and barrel need to all be made incapable of ever being used in a functioning firearm again. This can be done without being seen on the outside if you really want a wall hanger. I would hate to see it stolen and someone here end up with a new barrel, or cylinder as an inexpensive project component!! Safety first!
I would first do as recommended call Ruger, see about a discount if not,,,let them destroy it or you do as I recommended and make it unusable.
You might even talk to someone like Clements, or another custom parts manufacturer to see if it is possible to temper and harden it to safely use it again if you want to shoot it. I don't know if that is feasible or not, but can assure you he does, and there are others experienced in the industry that will. Good luck whatever you do,,,,but keep safety first!
