I have the opportunity to obtain some Civil War items. Included is a complete belt with a n 1851 Eagle belt buckle with applied silver wreath. It appears that the silver wreath was attached by rivets. Could this be a replacement or was that sometimes done in the past? Also, is the belt buckle an authentic 1851 Eagle belt buckle with a silver wreath. Please check out the front and back pictures provided and let me know what you think. All the items look quite old, but I realize there are many reproductions out there. Thank you very much.
