Niklas,

You are filling in some gaps that I did not even know existed. Your account of the low country Walloons (Wallon in French) migrating to Sweden makes a lot of sense to the later damascus trade. Sweden has the luxury of endless forest, unlike England. English forest was lost to building ships. So in addition to the quality of the iron the charcoal smelting was preferred by the damascus makers of Belgium.

I knew about dannemora iron and also oregrund iron. I have assumed they are one and same, that Oregrund is just the port. Is this correct?

Also, have you read much about the Russian sporting arms trade? I know they were producing damascus barrels, but have never seen one.
