Joel,

There are a couple of tartans commemorating a battle between Norwegians & Scots mercenaries in the 1600's, but I imagine that the tartans would be somewhat expensive to get for a kilt!

However, one option would be the Sinclair Tartan, since the Sinclairs have a long connection to Norway, especially Prince Henry Sinclair, who ruled the Orkney Islands. The Chief of the Clan Sinclair is also the honourary patron of "The Cally", the Caledonian Society of Norway.

Cheers and Fair Fa' ye! (welcome!)
