I just ordered one from Allan's Armory. He lists his rifles with individual descriptions of each piece. I liked that. Seems better than "luck of the draw". Especially if a supplier only has a few left, it would seem that even "hand picked" would only be from the dregs. I'll let you know and post a pic when I get it.
BTW, 7.5 Swiss ammo seems very hard to find. I ordered some brass and a set of dies from Graf Bros.
