Imperial Russian Belt Buckle
George brought back two belt buckles from his time in Siberia. One he gave to his son, one to his grandson. This is a picture of one of the buckles. After some limited research, I have concluded this buckle is an Imperial Russian Belt Buckle. From what I can gather it seems as though the buckles were probably used by the Cossacks. Otherwise, I'm not sure where George would have gotten them. the story is that he took them off of two dead bodies, a pretty macabre thing, but definitely not uncommon in war time.
Maybe someone out there knows more about this...
