My thought on this is, if you are going to keep it and use it do what you want. If you might sell it down the road, leave it be. It will ruin any collector interest. Good luck, and post some pics if you get it. I used to have a pre-64 in 264 Win mag in pristine condition. Our house burnt down and it was lost.[] Someday it will be replaced. But probably in a different caliber. Good luck
