Update first Button:
I retrieved a button made of brass, the face of the button bore the image of a three legged eagle and around the rim were the words Es Devs Spes Nostra. Having as a friend a priest who speaks Latin really helped. He later told me that the words in English meant " God Is Our Hope." Further research reveled that the eagle is a Teutonic eagle. The button may have come of a Hessian soldier, mercenaries used by the British during the Revolutionary War. However, modern "blazer buttons of this type are often found"
That sucka was deep about a foot in a 1800’s Park I hope it’s the original.
