I posted a link at MyArmory and Sean Flynt , kind gentleman that he is , offered the opinion that the blade is an English or European Backsword blade from the 18th or possibly 17th century .
My thanks to the gang over there , and thank you Sean .
This sword is huge by my standards .
The hilt was made for quite a large hand .
One would need a very strong arm to wield it with any success .
Another observartion I have is that the Rhino horn is quite splintery when cut along the grain .
