What sword is depicted in Duke of York statue?

I'm wondering what sword is depicted in the statue of Statue of Frederick Duke of York in Waterloo Place, Westminster, London? I don't know much about the "types" of swords and I needed to know the type for a story I am writing.Thanks in advanced (a picture can be found here: http://en.wikipedia.org/wiki/The_Grand_Old_Duke_of_York)
