Maybe I misread that but whoever said there is just one real German sniper rifle in the world doesn't have a clue what he is talking about. There are a lot of known sniper rifles that are definitely legit. They are not rare by any means. Expensive but not rare.
You didn't misread what I printed. I said it was a "rumor" and found it hard to believe myself. On the other hand provenance for a REAL German sniper rifle is as rare as hen's teeth. I have seen several such rifles in the US, one in the collection of a fellow that brought it home himself. He took it from a surrender pile and had it shipped home with proper documentation as a battlefield pick up. I have no idea where that rifle is now. Maybe one of his son's, all shooters/collectors has it. That would be a good thing.
