At first that was my thought to, however since the fuller is rather short I don't rule out the possibility that it could be the blade of a dagger, but you are right it could just as well be a re-used rapier blade.
You gave me something to think about with the shell shape on the guard this shell shape also comes back in the form of 16th C Italian pommels.
All this does not have to be unusual at all since many rapiers and swords used by the Spanish were often of Italian origin.
