Jim and Iain,
To me the hilt of the Ethiopian regalia sword looks very much like the hilt of a sword sold through Hermann Historica, pictures saved in this thread:

There, it was described as a late medieval sword from Egypt. I agree with Jim that the single fullered blade looks very much like a Solingen made blade from the mid 19th century, but the hilt may be quite older. Or, the "mameluke" sword may be from a later period.
Regards,
Teodor
