Excellent examples of the South Arabian (Yemen/Hadhramaut) styling and of course the variation of the hilt, yet with the distinguishing 'hand nock' on the inside of the grip which seems to ideally denote 'nimcha'.
While obviously we are deviating from Charles' sword in the original post in degree, it is interesting to examine the spectrum of styling in these Mediterranean swords which are typically associated with Algeria.
The development of the form from 15th century Italian hilt styles, and blades evolving as well from Italian stortas and European falchions also provides dimension in understanding the dynamics and context in which Charles outstanding example originated and clearly held importance.
I think this Somali connected topic as well as others which have come up in examining Charles' nimcha are well worthy of their own threads to be discussed further. I never had heard of this Somalian kingdom either! but its fascinating to see the world this nimcha lived in !!!
