Richard M. Nixon's Browning Auto-5 is known as the gift-that-wasn't. The A-5 was to be presented to the President by Senator Bob Bennett (R-Utah) in 1970. The spectacular, ornate 12-gauge shotgun came with a modified choke, a 28-inch barrel, and a 2 3/4 inch chamber. Elaborate scrolling, gold inlays and a highly-figured walnut stock paled in comparison to the fact that the serial number for this A-5 was 2,000,000. Nixon declined the gift, leaving the A-5 to be stored in the Browning archive vault. After 15 years, the shotgun was loaned to the National Shooting Sports Foundation for display. In October 2015, the shotgun was sold by the legendary Maine auction house, James D. Julia and Sons. The winning bid? A cool $54,625.
