The original ‘Dann’ bomb sight used by the famous World War Two Dambusters squadron is to be auctioned in Northamptonshire.

The sight, used in Second World War aircraft to accurately line up bombs, is among the items passed on to J.P.Humbert Auctioneers in Towcester by Hydneye House school.

The school was originally given them by the family of David Maltby, pilot of the Lancaster bomber that, in May 1943, breached the Mohne Dam in Germany with a bouncing bomb.

Brainchild of Wing Commander Dann, the mahogany bombsight on sale was used in the successful raid.

It is thought to be the only surviving example of the sights used during the Dambusters raid and its value is estimated at £20,000-£25,000.

Alongside it, Humberts is auctioning the map light and parallelogram used by Maltby’s navigator, Vivian Nicholson, on the same Lancaster bomber. All three were signed and verified by George ‘Johnny’ Johnson, ‘the last of the Dambusters’.

Also available are four of the marbles used by Dr Barnes Wallace to help design the bouncing bomb and along with Guy Gibsons’ leather collar box, all separate lots.

Auctioneer Jonathan Humbert said: “Of all the exciting items that have come under my hammer over the years, these have to rank as some of the most spine-tingling and historical.

“An integral part of modern British history and synonymous with heroism of the highest order- we are very proud to offer these items for sale and, given their excellent provenance, we are hopeful for a great result.”

The sale will take place from 5pm on Tuesday, January 20, during the International Militaria Auction at J.P.Humbert Auctioneers Ltd Towcester.
