Thank's again for your comm ! I just change picts which, I hope, are better
Thank's Kubur, I don't knew this area and this is a nice discover.
The little bit on the hilt are "shell's nacre", something unsurprisingly for a hilt which would be done in the red sea's coast area.
After all the blade and the cross guard can pre date the hilt, if the blade and cross guard were recycled of an older European sword and after trade in Africa isn't it? I've seen/read that was a common practice ?
