Hi Ibrahiim,
The mark, along with many other European crosses, is largely derived from the Greek cross and you can find many cross marks with either fork terminals, or straight, Maltese or many other designs. So I think there is some superficial similarities with all Coptic crosses.
This blade and the marks are entirely European and I think the entry point into the Sahel is likely to have been Egypt or Tunisia. About dating I really hope it is 14th century as well and I see no reason at this point to think it is not.
Jim,
Brilliant as always! Very helpful material, Italian seems a very likely attribution. The idea of the blade moving with the Mamluks, either by trade or war, is a valid path to consider. My reason for suspecting an early date for the hilt is mainly the difference in construction and the pommel. If we use the two examples from 1830 as a benchmark and consider those styles in vogue for +/- 50 years, we are already back in the late 18th with those two swords. I think it is fairly reasonable then consider an 18th century date for this one. It is quite lucky for me this wasn't rehilted more recently!
Thinking about the Mamluk connection, it strikes as odd these haven't turned up in kaskara hilts as well... This was the pinnacle of the gold routes and large numbers of traders would have been moving with the great camel caravans.
