Bone buckle with incised interlace pattern on buckle plate. Description and illustration (figure 19.6) in Waterman 1959, pp. 91-92: 'Both [buckles] are cut from a single piece of bone, in one case with a separate tongue which rotates on a pivot of the same material. The method of attachment to the belt differs. The complete example, with an engraved interlaced knot on the plate, is provided with a notched projection to pass through a corresponding hole cut in the material of the belt.'
