Hi Tim and Lew,
          thank you  

  do you think this is from the Mandara region?
   I am impressed with the quality of the blade.... still quite sharp.....I'm fairly certain that this is a native blade and not a re-worked European one. 
  Will post some close-ups (later) of the forged pommel ...with its raised 'border'...in case it will aid ID
 Kind Regards David
