Ariel, 
 
Good snag.  I noticed that one also and could see even from the poor pictures provided that the blade had a nice pattern welded blade.  Also, I do not believe the hilt to be brass.  Look closely.  It appears to be an old gold leaf on a steel or iron hilt.  I can see a bit of the leaf wearing out in spots.   19th century is the safest estimation of age but I wouldn't be surprised if it was late 18th century.  Just a gut thing though.
