I recently picked up these 2 spoons at a great price but I'm a little unsure about the stamps. I know the lion means it's sterling, that's why I picked these out of the pile of plated flatware. After some research I believe the duty stamp is GeorgeIII which puts these in the late 1700's-early 1800's. The date stamps "S" and "T" might be 1813-14 and the Maker's mark "GW" for George Wintle. Can anybody confirm this for me? Any help would be greatly appreciated.
