Yes, it sure does. Can you tell us its length ... excluding the tang ?

Sure thing; it could well be from the XVII century.

This blade could (could) have been mounted on a cup hilt sword, although that grip wrapping style is not so usual seen ... i guess; as also this could have been from a different sord.
