 Thank you for that follow-up, Phoenix7777.  Given this background, I'm perfectly happy for these sources and related text to be removed.  My main concerns with the anon IP were 1) changing (what I thought was) properly cited text to say something different, and 2) making a claim with a new apparent citation, but where that citation does not back up the point made (about the forging techniques being the same as those in Shandong).  Your research above resolves my concerns about point 1.   Cheers,  │ Tala við mig "
