No problem Wayne! You are most definitely thinking
, and again, you are doing well at using deductive reasoning. In this case however, the sword is what it is, just as Ariel has very well explained.
There were indeed many trade blades that carried spurious 'Genoan' markings found throughout the Maghreb. What made this blade unusual is the linear sickle mark motif, and the backsword profile, and as again, Ariel has noted, has nothing to do with the slightly curved, shashka type blades often found with the Genoan mark.
All the best,
Jim
