large old sword with strange hilt ( crescent shape guard ?)

[BBking]

I receive it,
just clean a little for look the hilt and the engravings,
the hilt must be more recent than the blade but it is really well made,
much more than I imagined, I think made of silver parts and it was maybe early gilted on some parts,
really nice the work on the '' crescent guard parts''
with small circle and rays like suns ? in what must be animal (?) scales ?
the ends can be a claw ? so maybe it represents eagle claws ?
Engravings ont the two sides of the blade until the fullers but sadly we can't see that much anymore...

the blade is not large but really thick and really thin and sharp near the tip,
as Ariel wrote , it was clearly longer before...
