Concorde G-BBDG (British development aircraft) test wiring (30cm)

Removed from G-BBDG by an engineer, this 30cm length of wiring was used as part of the testing sign off of the UK side of the Concorde development programme. As shown in the photos onboard some of the Concorde used in the test cycles, it provided data back and forth between various systems within the aircraft.
Also comes with certificate of authenticity.
Photographed here a section example on the main landing gear and underneath of one of the engines of G-BOAC at Manchester.
Price is for one length 30cm- photo is example
This cannot be bought anywhere else- extremely rare.
