Gopher,
Yes, the american basswood is in fact linden, the carving wood. I figure there was a reason they used the "soft" woods, just aint figured that out quite yet.....but I'm sure there was a reason.
aero,
I dont know why there seems to be so much Danish in the finds, but for the shields they been dug up in Denmark, Norway, Latvia, the British Isles and some in Germany and Russia (Russ). Maybe some of the other fellas that do the diggin just didn't post their findings or something. If your just starting in on the whole Viking thing try to remember they were not divided up like today, i.e. Sammi, Norway, Denmark, Sweeden and the like. They divided them selves by warlord aligience, and with groups that were interested in exploring either Eastward or Westward. Some of the groups went to Iceland, Greenland, and the North America's and a bunch went into what is now Russia, Balkins and damned near to India and China. And both groups went down to harrass the British Isles, France and the Mediteranmian areas. Just to make a point, pure metals (like copper) can be traced to point of origin by their impurities makeup. Well, they found great lakes copper metal in what's now Iraq (find dated to 900), and I'm pretty sure the NA guys didn't paddle their 30 man canoes over there, so that kinda leaves them Viking dudes.
hopethat helps some.
