Salaams All, Note to Forum; I discovered this interesting shot by Michael Blalock in another lead at 
http://www.swordforum.com/forums/sho...ons-and-armour at post #3 bringing the question to that of the Wallace collection again. See #14 on 
http://www.vikingsword.com/vb/showth...hlight=wallace  These swords appear to be of Yemeni pedegree though there appear to be two qualities...viz;
 
1.The quite basic variety that we have been dealing with which could perhaps be Yemeni Askri(Palace Guard/Militia)  weapons and 
2.The very highly ornate Wallace collection/ ornate version seen in para 1 above quality.
