Provenance is always hard when it comes to these types. When you think about it, even some of the issued naval swords, such as the old m1803 Brit, were often post-war swords used by merchantmen or shipped off to other countries entirely.
With this cutlass type, at least I think we can reasonably say that it's either british or American. This sounds redundant, but when you think about all of the other navies around at the time, that really is a narrowing of the market. I've never seen any of the other naval powers (Dutch, Russian, Spanish) with this pattern of cutlass represented.
