What do you think about the attached saber?
Seems that it may come from Algeria, or Yemen... for me it looks like more from Yemen (hilt type) based on other posts:
Blade is polished and was engraved (not much has survived).
Blade quality seems to be good. Maybe older than hilt and scabbard..
Would appreciate more information about the origin/age
Mounts are definitely Yemeni work. Those blades, including on nimchas, seem to have been present in Yemen in large numbers and can come on a variety of swords including 'karabelas' and other types.
