Argo,
The Col. who wrote the article for The Rifleman brought back a Darne. The Marine I knew was likely a SSGT at the time he brought back the little girl he named Beth. I have no idea what his rank was at retirement, which would have been early 1980s.
He has since passed away, but, was one of the toughest individuals I've ever known.


Larry,
Tim Carney had a Darne 10 reproofed, and had an article in DGJ on the gun. If I am not mistaken, he didn't get the level of proof he asked for, and the barrel work that was done in France had to be corrected by Kirk Merrington when he got the gun back. That part didn't surprise me, when I read the article, which, I don't have at hand.
I don't recall ever seeing kilos marked on a French gun-if it passed proof, it got the crossed wheat marks of the St. Etienne proof house applied at whatever level of proof had been requested. Even if the numbers or system changed, the marks stayed the same, at least for the last century.
This could have changed.

Best,
Ted
