A medical card filled in by a plastic surgeon after Lord Lucan broke his nose in a speedboat accident has sold for £100.
Dr John Watson of Harley Street detailed the aristocrat’s injuries and drew a sketch of his nose. It sold at Duke’s Auctioneers, in Dorchester.
The 7th Earl of Lucan vanished in 1974 after his children’s nanny was killed.
His cousin Victor Bingham said the notes could be valuable for any future investigations into his disappearance.
“If they ever find the body, that would be a very important clue to help identify him,” he added.
The note, written in 1963, refers to Lord Lucan by his real name, Richard John Bingham, and his then age of 28.
It reads: “Struck nose on steering wheel of boat… profuse bleeding at time.
‘Soaked in blood’
“Now – Laceration floor of nose Rv. Vestibule. Compound dislocated septum with fragment projecting into Rt vestibule.
“Nasal lanes appear intact.”
The medical notes sold at the Dorset auctioneers for £100, plus a buyer’s premium of 19.5% and VAT.
While it had a guide price of between £100 and £200, spokeswoman Amy Brennan was surprised it did not go for more.
She said: “There’s so much interest in all things related to Lord Lucan.
“I thought it was exciting that if his body ever came to light it would be a fantastic way of identifying him if they x-rayed his nose. It could become really, really important.
“The fact that his surgeon kept the notes is also intriguing.”
Nanny Sandra Rivett was found dead at the home of Lord Lucan’s estranged wife in the Belgravia area of London in 1974.
Lady Lucan was also attacked but managed to escape.
Lord Lucan disappeared and his car was later found abandoned and soaked in blood in Newhaven, East Sussex.
A year later an inquest jury ruled that Lord Lucan killed Ms Rivett, whom many believe he mistook for his wife Veronica.
Lord Lucan was officially declared dead by the High Court in 1999.
Since his disappearance at the age of 39, there have been more than 70 reported sightings of him in countries across the world including South Africa, Australia, Ireland and the Netherlands.
