Dear Max: I'm fairly confident that the Walloons below are not the Walloons you're holding in the bag...and this probably belongs on the mill thread. But in the spirit of the Great Steel Bearings, here 'tis a bit of trivia:

The iron-ore was the base of the Swedish steel industry during the 1600-1700s. The father of Swedish industry, Louis De Geer, brought his skilled workforce to Sweden from the Netherlands, Walloons to be precise. That is why the factories came to be known as Walloon mills. The Walloon steel soon became famous for its "sound" and "body". The English blacksmiths chose Walloon steel when high quality was required.

Beast regards,
