If we speculate about routes for the beads from the Atlantic instead of from Siberia, there are at least four vage possibilities: a) A route from the Caribean European settlements established after 1492 b) A route from New Foundland fishermen bases established around 1500. c) A route from the New Foundland Viking bases from the early 1000s. d) A route from Norse Greenland (980s to late 15th century). Possibilities a) and b) are likely too late regarding the dating. Possibility c) is too early (no Ventian beats in the early 1000s). But d) seems to me at least as plausible as a Bering Strait route.
