Commemorative Limited Edition #0143
This was marketed by "The Edge Company" in their 1988 catalog.
I am not sure of the manufacturewr of this piece but it is marked Sheffield England on the grip side of the crossguard.
It is also marked on the grip side of the crossguard with S.A.S. LTD EDITION 0143.
This is basically a 3rd pattern FS knife wirth a Who Dares Wins badge pinned to the crossguard. It came in a very nice wooden box with a brass plaque on the face that reads
"WHO DARES WINS"
