Aerospatiale-British Aerospace Concorde laser engraved onto genuine Rolls Royce RB199 aircraft engine compressor blades made into a lovely cufflink set complete with display box.
 
These compressor blades are genuine Rolls Royce RB199 blades and have been in service with the Royal Air Force on a Panavia Tornado F.3. They have flown at Mach 2, twice the speed of sound which is an incredible piece of engineering. Cleaned and polished, they have a lovely finish.
