[katana]

Hi everyone,
picked this up, the hilt seems to be bone with horn pommel and guard. The blade is 'flyssa' shaped, tempered steel with parallel ground fullers, overall length is 37.5 cms, blade is 26.5 cms.
I believe this is North African, the inscription on the blade will surely provide clues...only problem is I dont recognise the script and cannot translate it. The cresent moon with star motif is also on the other of the blade but the script is on one side only. There's no scabbard.

So please.... any ideas, comments etc welcome ...thankyou
