Blacksmith realistic?

[Danest]

Here's how I see the blacksmiths as being potentially realistic (though I agree that they're a problematic building)... Let's imagine that Sweboz archers (I'm making up examples, I don't know if Sweboz archers exist) conquers a gallic town with a much more advanced metalwork facility than his little german village had. I can't help but think that the sweboz archer could take note that this gallic town produces a much higher quality of iron, and sharper arrowheads through its superior "blacksmith" building. He'd be able to replace his old crappy german iron arrowheads with the superior gallic arrowheads - this seems quite possible, I'd. This would be an entirely different act than recruiting the local archers from the MIC, who might very well be different from sweboz archers on issues other than just iron. Perhaps building a "blacksmith" building in the town represents that the town has men in it that have a higher understanding of metallugy (maybe they would require a mine to be in that town first, thereby limiting the number of these facilities?) I'm sure such places must have existed, that were entirely seperate from the kind of military training offered in that town (MIC/Barracks).
