No clue what it is! any ideas? Please let me know. Regards

News from the 3 march 2012

From Mr Robert Wilkinson-Latham: The Proof slug and surround are most certainly that of Robert Mole. 
Also it looks like a English Presentation sword late XIX century
...may be for an Army doctor or vetenerian ...since a Caduceus is found on the blade???!

Marked " PROOF"

 A caduceus from a Medical or Vetenary corps?
