Interesting rifle with an interesting story. So this unidentified U.S. Army officer just plucked this gorgeous rifle out of burn pile in 1945 and walked away with it? You'd think the French government would have a claim on it.
It says "the gun was in as found, closet condition. Some of the elaborate wire inlays in the stock were loose, there was also a crack in the stock near the rear of the action, and a few other rather insignificant imperfections, which included a couple of small missing pieces of silver and a replaced mother-of-pearl portrait hidden beneath the lid of the stock. The gun was properly and thoroughly cleaned and what little restoration work that needed to be done was done in the finest order by one of the foremost authorities on early firearms restorations...."
I think the burn pile was confiscated guns after the German surrender. Considering all the damage inflicted throughout Europe the French government probably had other things to worry about than an old relic from Louis XV. A German soldier had probably looted it and when disarmed it ended up with other guns to be destroyed.
