A handgun once owned by notorious gangster "Al" Capone will be going up for sale at a London auction this week.
Christie's auction house says that the Colt .38 revolver is expected to sell for 50,000 pounds ($80,899) to 70,000 pounds ($113,258).
It said Monday the gun is being sold by an unidentified private collector. It says the gun was manufactured in 1929 _ the year of the St. Valentine's Day Massacre, in which seven people were murdered slain during clashes in Chicago between Capone's gang and a rival gang.
The pistol will be sold along with an original letter from Madeleine Capone Morichetti, the widow of Al Capone's brother Ralph, confirming the gun "previously belonged to and was only used by Al Capone while he was alive."
The gun will go under the hammer on Wednesday.
