Salaams dstockbridge, Ivory hilt...If what I am looking at is a wooden scabbard then possibly Ebony...or another hardwood.... The weapon is full of patina ...and I would be very careful before attempting a restoration...start at the bottom of the scale with coke cola on the blade and rinse every few hours.... I see damage on the hilt....and clearly this is a most careful proposition for cleaning ....Take your time. I can tell you that a lot of people would say don't do anything to it at all!...
