Very nice cuff links. I have seen these debated ad nauseum in the detecting community. Neither side presents any definitive proof. On one side you have the advocates for these being civilian. I can definitely see their argument because quite a few Tudor Rose and similar buttons are found and they can't all be Royal Navy, can they? On the other side there are at least two websites that say these are Royal Navy. Those sites include the mid-1700's uniform regulations as "proof." I have been searching the internet for three years trying to find period advertisements as, to me, that would be the proof sufficient for a definitive ID. Also, the mourning buttons attributed to George Washington lack the same kind of proof even though one of the website owners claims to have such period advertising. I'm not from Missouri but, "Show me."
