A sight used to guide the Second World War bouncing bomb has fetched £41,500 – twice what it was valued at.
The Dann sight, used during the Dambusters raid on the Mohne dam in Germany, was auctioned off along with marbles used to design the bomb itself which sold for £27,200.
A map light fetched £2,700, the parallelogram used by flight navigator Vivian Nicholson sold for £2,650 and the leather collar box once belonging to wing commander Guy Gibson went for £750
Remnants of the Perspex bomb-aimers bubble used by surviving Dambuster, George ‘Johnny’ Johnson, sold for £520 which took the grand total to more than £75,000.
Auctioneer Jonathan Humbert said: “The overwhelming interest we have had in these items is testament to the bravery and heroism of the men who risked their lives in Operation Chastise.
“These historical items, much like the story of The Dambusters, have really captured the imagination and I am delighted that the auction was met with such resounding success.”
It was the bouncing bomb, guided by the sight in 1943, which breached the Mohne dam and flooded the western Ruhr region.
The Dambusters lot was the latest in a series of bizarre items auctioned off at JP Humbert Auctioneers in Towcester after Jack the Ripper objects fetched £17,000 and Charles Bronson artwork sold for more than £30,000.
