RR Auction, which hosted the sale Sunday in Nashua, said Bonnie Parker's Colt .38 snub-nosed revolver sold for $264,000, while Clyde Barrow's Colt .45 sold for $240,000, CNN reported Monday.
The auctioneer said Parker's revolver was taped to her leg and Barrow's was found in his waistband the day they were both killed in a shootout with police in 1934.
"These amazing and historic weapons were found on the couple the morning of their deaths and gifted to Capt. [Frank] Hamer, along with other items from that ill-fated day, on May 23, 1934. The guns, along with other items, were taken by authorities at the time as part of his compensation package for the ambush," RR Vice President Bobby Livingston said.
The auction house declined to identify the sellers or the buyers.
