A remarkably rare collection of firearms tied to some of the most notorious figures of the Depression-era American underworld is hitting the auction block. Vandenbrook Galleries in Tampa, Florida, has announced the liquidation of a billionaire’s private, historic gun collection. While the auction features over 100 highly collectible military and civilian firearms, the centerpiece lots are heavily documented weapons attributed to outlaws Bonnie Parker, Clyde Barrow, and George “Machine Gun” Kelly.
The undisputed crown jewel of the collection is a Model 1897 Winchester 12-gauge pump-action shotgun attributed to the infamous bank-robbing duo, Bonnie and Clyde. According to the extensive documentation accompanying the firearm, this shotgun was seized by Missouri police on April 13, 1933, following a deadly shootout with the couple in Joplin, Missouri. The weapon’s provenance traces a fascinating path: a police officer reportedly gifted the shotgun to Mark Lairmore, a Tulsa, Oklahoma police officer, and it remained in his family for decades. The gun was even displayed at a police museum in Springfield, Missouri, from 1973 until late 2011 before entering the private collector market.
Equally compelling is a John Price single-shot 12-gauge shotgun attributed to the notorious gangster Machine Gun Kelly. This firearm carries the physical marking “Boss Shannon,” referring to Kelly’s relative by marriage. Historical records indicate Kelly used this specific shotgun during his high-profile kidnapping of oil tycoon Charles Urschel. The weapon's journey is a piece of Americana in itself. Kelly’s mother-in-law, Ora Shannon, originally gave the shotgun to Benny Binion, the legendary owner of the Horseshoe Casino in Las Vegas. The gun sat in Binion’s casino vault until 1985, when it was given to Billy Bob Barnett of “Billy Bob’s Texas” fame, before finally making its way into the current billionaire’s estate.
Beyond the Prohibition-era gangster weapons, the estate sale also includes significant European military history. Among the lots are three German Luger pistols accompanied by highly unique acquisition records. These specific Lugers were reportedly surrendered by German forces to Norwegian authorities at the close of World War II. They were later formally acquired from the Norwegian Armed Forces Museum in Oslo and imported into North America, retaining their full museum provenance.
Bidders have the option to participate in person or online through digital auction platforms. The event is drawing intense interest not just from traditional firearms collectors, but from museums and investors in true-crime memorabilia.
The gangster-era firearms market is completely dictated by the strength of its paper trail. A standard Winchester 1897 is a $600 working gun; a Winchester 1897 with a verified Joplin shootout police seizure record is a six-figure museum artifact. The Vandenbrook auction highlights how true-crime provenance creates a massive multiplier in value. For the broader 2A community, these auctions preserve a darker, albeit historically vital, chapter of American gun culture where the line between lawmen and outlaws was often dictated by the hardware they carried.
