Similar blade with short fuller:
I would say that this is how your blade started.
Visible fuller length beyond cup/guard on my sword is 10".
I would place the date of the reconstruction to possibly end of the 18thC but more likey early 19thC (as Jim said).
Despite the fact that this is made from a reclaimed blade, I think that it is of rather good quality. The mounts remind me of the Napoleonic era. There is an almost naval dirk look to the whole piece also.
Rather interesting.
