Absolutely stunning pair!
I don't have time right now to hit the books and try to learn anything about the maker, but in my opinion they're probably from 1810-1820.
What kind of papers were they kept with? I'd assume anything with a filled gold watch and those razors would be important to whoever hid them.
Neil will almost certainly turn up a volume of information on them, but I think he's currently away. At least his website currently says he'll be away from email until the 15th.
When I get some free time I'll see what I can come up with.
