Well folks, I did it - I finished the restoration of the guard of this puppy!
The bottom half is made of seacow bone sent to me from the previous owner (and I colored to better match the rest of the whalebone). Had to use silver pins since the whalebone was too porous for glue. The looped guard is silver in the form of 2 naga/snakes and the heads coming out of the other side facing each other with copper eyes (did my best on the heads

). Here are the pictures as promised.
Enjoy -
