Five .38 caliber S & W cartridges found in Chicago’s Lexington Hotel. Rounds are housed in a 2 x 2 square box and were found on top of a steel beam in the hotel’s basement. Capone carried a Colt Police Positive revolver in this caliber, although it is unknown if these were for that particular gun. Bullets are lightly corroded. In later years many gangland historians, curiosity-seekers and souvenir hunters slipped inside the building, previously the Lexington Hotel, and salvaged whatever was convenient. Accompanied by a letter of authenticity from well-respected gangland historian Bill Helmer. RR Auction COA.
