The later FOTW description gives an approximately 1:2 flag quartered diagonally red and blue, with a white square diamond nearly touching the top and bottom, charged with a black N. Rosanoski questions its origin: the cited pages showed only a link logo, not a flag, and the linked company site supplied no confirming image. He therefore leaves this reconstruction unexplained.
