Bjarne Nielsen had a number of different lines. The Handmade pipes were just that. Individually handmade and one of a kind. They were quite reasonable for a one-of-a-kind piece. I have a few of them, including one the Bjarne had made for me as a gift.I have heard of Nording pipes but like you I'm not familiar with Bjarne. Evidently, Viking pipes are Bjarne seconds. (?)
Bjarne Vikings are not a second, but they are mass-manufactured and available only in standard shapes and finishes, and the stems come from blanks rather than being hand cut.
