PLEASE see http://www.vikingsword.com/ubb/Forum1/HTML/000370.html
for an interesting debate on these weapons.
At post 25 above I considered the blade stamp marks as Algerian and I still do ~ with the name of Ali bin alwafi bin Hassan on the cuff region . At the same time I consider these to be Bukharan weapons but cannot rule out that Jewish Smiths in Yemen may have made some of these as Micheal Blalock has indicated. However, I see no relation between these and Omani Swords.

Below. It could be that the Algerian sword and gun marks are the same as the three dense black stamps on the sword.
