Hi Royston, nice find
I hope Artzi doesn't mind, but found these images, not exactly the same, no human head but overall quite similar. What are the dimensions of the blade and do you think it is functional. The reason I ask is that awhile ago I found a Kastane hilted straight bladed example...which turned out to be a 'popular', suitably exotic looking sword ..often used by belly dancers
(belly dancers ...not the sword
The European (looking) head is very interesting, and I hope that your example is indeed, old and not a 'copy', I have seen a couple that were Victorian wall-hangers...but the blades were just for show.
Kind Regards David
