As I said earlier I managed to remove almost all of the water stain on the butt stock. Here are before and after pictures of the right side of the complete rifle.

I stripped the stock with a furniture stripper several times before using Oxalic acid on two separate occasions to remove probably 95% of the stain. I then used a stain conditioner on the whole stock to get a uniform color followed by a coat of a Provincial oil stain. I then put 6 light coats of TruOil finish and allowed the stock to dry for several days. Then used rubbing compound to take the gloss off and finished with Birchwood Casey Stock Sheen and Conditioner. The metal parts were wire brushed. The butt plate screws and sling swivel were treated with a rust remover while the butt plate itself was sanded with fine sandpaper. They were covered with three coats of Brownell's semi-gloss black Aluma Hyde ll and baked in the oven between coats. I an still considering what to do to the original cleaning rod to preserve and restore it.
