I'm not sure about cigar-shaped pin-beaters, like in Anglo-Saxon finds, but to be honest, I never looked for them really. One, quite similar, is mentioned in Nancy Edwars book
click.I know for sure there are wooden weaving swords from Dublin and other sites - good description of them you can find in "Viking-Age Decorated Wood" by James T. Lang.
And speaking of loom weights, if I got it right, the CF structure I mentioned before, is dated to mid-late ninth century.
Some info about loom-weights can be found also in brochure "Crafts" in "Aspects of Viking Dublin" series by Pat Wallace: "Direct evidence for looms is disappointing, although small stone cylinders which are commonly found are thought to be loom-weights."
I'm off on Wednesday, so I think i'll go and check the Viking exhibition in Dublin museum, maybe there are some weaving implements I missed.
BTW, I had the same problem with little squares as well
