Two guns that were in the possession of notorious gangsters Bonnie Parker and Clyde Barrow when they were killed in a hail of gunfire in 1934 sold at a New Hampshire auction Sunday for more than half a million dollars. The guns were two of 134 artifacts that sold for a total of $1.1 million at the auction in Nashua. About two-thirds of the auctioned items were from the famed crime couple, but items also came from other notorious criminals, including Al Capone, Pretty Boy Floyd, and John Dillinger. Parker’s .38-caliber detective special drew the highest bid and sold for $264,000, said Bobby Livingston, vice president of RR Auction in Amherst, N.H., which held the auction. Clyde Barrow’s 1911 Colt .45-caliber automatic sold for $240,000 to the same bidder, who did not want to be named, Livingston said. Many of the auction items came from the estate of the late collector Robert Davis of Waco, Texas, with the remainder coming from various other collections.
