Hey Tony thanks for the warm welcome..I see what you are saying but having 4 flowers it could have been worn either way..
It's hard to tell the size with no comparison but i think it could be a hat buckle..Actually the more i dig deeper into thinking about it the more i am convinced it's a hat buckle..Knee buckles always have the pins on the shorter side..The ribbon around a hat is wide hence the wide pins on this buckle...Seems way to ornate to be worn on the side way down there..That baby was made to be looked at head on..Interesting..
