Silver hilted

[urbanspaceman]

I recently acquired this silver hilted smallsword. The hilt is one of the finest I have ever seen but, unfortunately, the maker's hallmark (London) remains a mystery even after many hours of searching. Does anyone recognise it? It's possible it is an early Andrew Folgelberg (the standard is certainly worthy of him) and thus what we see is an AF; because nothing else out there even comes close and considering the date is about right 1760/70, I am giving it consideration. Anyone any-the-wiser, please...
PS
According to my colichemarde blade theory, posted earlier, this is a Shotley bridge (Oley) blade.
