If you go to the 'Museum of Berkshire Aviation' located on what remains of the old Woodley Airfield, nr.Reading, RG5 4UE, you will find the one remaining example of the "Fairey Jet Gyrodyne". This appears to have been a 'proof of concept' test demonstrator for the Rotordyne. Two were built, one crashed if I remember the notes correctly. Worth a visit for the other exhibits on display.
With fraternal greetings,
