Mole court-sword conundrum

[urbanspaceman]

I wanted a Mole sword to form the final gasp of the entire Shotley Bridge affair, but I was looking for something a little more flamboyant than one of the tens of thousands of munitions grade swords and bayonets they produced; then I came across this one.
I fitted the bill perfectly and the blade is as good as any out of Shotley Bridge or Solingen, except I have no idea what it was in aid of.
I wondered about The Tower Guard or perhaps Parliament, but these were just uninformed musings. Can anyone identify this sword please?
