I recently acquired a Kaskara along with a late 19th century English sword. I’m wondering if there’s a chance that it might have been a “bring back” from the Mahdist Wars or is it just a “tourist” piece? Any information on this piece would be greatly appreciated.

Thanks,
Len

P.S.
What is the calligraphy on blade? I don’t believe it’s Arabic.
