‘Fragment of the ‘Little Boy’ Atomic Bomb’ is an item of militaria. The fragment appeared on the market in February 2010 priced at £15,000. The bomb

The Mk 1 bomb, nicknamed ‘Little Boy’, was the first nuclear weapon used in warfare. It weighed about 9000 lbs and “produced an explosive force equal to 20,000 tons of TNT.”

The bomb was the result of the Manhattan Project, “perhaps the greatest secret project of the 20th century”. Started in 1942, the project was a reaction to “fears that Nazi Germany would build and use a nuclear weapon during World War II”.

‘Little Boy’ was delivered by B29 Enola Gay, and detonated 1800 feet over the Japanese city of Hiroshima on 6th August 1945.

Approximately 66,000 people were killed by the blast, although by the end of 1945 (due to the effects of fallout) this was thought to be over 100,000.

The fragment

After the construction of ‘Little Boy’, the 13,000 consultants and scientists working on the project took or were given “souvenirs”. One of these was a “160mm diameter ball race” from the construction of the bomb.

The fragment was “micro engineered” and is “one of a pair acquired from the collection of the late Professor Samuel Eilenberg, Professor of Mathematics at Columbia University in WW2.”

It is “64 years old” and has been described as “central to the construction of ‘Little Boy’”.


Its importance, age, rarity and connection to an historic, if tragic, event, make it very valuable.

The fragment appeared on the market in February 2010 priced at £15,000.
