Hi Stephen,
I too followed this auction because of the 'eyelash' markings....usually associated with mainly Indian blades.
So, either this is a re-worked (?) Indian blade (possibly) or the marking has been 'adopted' ...as the 'half moon' was from earlier trade blades from Europe.
Seeing as there has been sea trade between India and the East coast of Africa, for centuries and, the overland Arab trade routes for even longer ...I can see no reason that the Kaskara is not genuine.
I wish I could have bid (damn credit crunch
) ...it is the first I have see with such markings.
Kind Regards David
