Hi Gordon,
Yemeni sword. I once had 3 of these with very similar scabbard decoration but they have since been "passed on". The 3 I had, had different shaped blades, 1 was like yours with a straight blade. The other 2 had curved blades, but the scabbard work was similar to yours with white metal chape and drag and the wound metal along the scabbard length.
Not sure about them being used in actual combat but nice anyway.
Hope this helps.
P.S If you wish to PM me for "off topic" questions please feel free.... Or email
