As everyone has commented, it is a shame about the hilt. I know this form as Garantiman, but i believe Frey has used the word Grantim as Henk has stated. The snake-like piece you describe i believe is supposed to represent a lotus sprout. Though only made of brass, i would still say this was a nice example as it is actually woven material, not just a cast piece of metal as some of the later examples of this form were.
The mendak does look more like an adaptation than an authentic piece, made to fit better with the bone underneath.
The blade is not unattractive, and in response to Jose's comment, if it was offered to me for sale it would all depend on just how much it was offered for.
