Just can't leave this one alone. I am more and more convinced that it might be older than discussed, perhaps 1810-20. Take a look at this site, example #2 for simolarities...

Later cutlasses had hilts that were more shaped to the hand, versus the plain wrapped sheet iron grips of the earlier pieces. Ribbing started with the m1803 and seems to have continued up to the m1845 Brit pattern. I will post pics of my newest acquisition (
) soon. Another cutlass with VR markings, but definately early Victorian, ca. 1840.
