Hi Gene,
Indeed a very different pommel..but it looks old though.
I also agree that the windings and the ferrule (is it damar?) are latter.
The scabbard I would leave it in the condition it is now. If you remove the dark stain, you probably will get a very "naked" scabbard....
Very different scabbardtip also....
I like the blade, and it looks old to me.
Can you see if the elephanttrunk has broken off in the past?
Kind Regards,
Maurice
