Baz69, personally I don�t think this knot to be of the 3R period. I do know such additional looking stitching on the strap only from sabre portepees, on troddels those lines normally are woven in. Just my thoughts.
Will be interested what Houston will tell us. Perhaps you are showing it in his forum?
