A Krupp stamp by itself means little or nothing.....
Au contraire mon frère, a Krupp stamp could mean everything. Unequivocally, the scattergun tubes posted were sourced from Liege & under the Sauer Wildmann trademark.

OK, I'll concede that a Krupp stamp could mean that barrels were made from Krupp steel. In fact, that would probably indicate a very high probability that they were made of Krupp steel. Unfortunately, as we have seen, a Krupp stamp could also mean they were stamped incorrectly, as in the case of Damascus "Krupp" barrels... something we know Krupp did not either produce or license. Hence my statement about a Krupp stamp meaning little or nothing, when it comes to being certain about the origin of a gun barrel. There have also been fake or counterfeit upgrades which have been stamped or engraved with Krupp or Whitworth, for example, in order to deceptively convey that a gun had the higher quality steel used in higher grade guns. And I'll stand by my comments about the futility of attempting to identify the steel supplier for a particular set of barrels by analyzing a piece of steel taken from them by any means... and most certainly not by centrifuging a solid piece of gun barrel.
