American sharpshooter and entertainer, Annie Oakley's 1883 16-gauge Parker hammer shotgun is expected to fetch 60,000 pounds at auction.
Besides her first and her favourite shotgun, another item for sale is her treasured charm bracelet, also expected to fetch 60,000 dollars.
US auction house Heritage is selling the memorabilia in Texas, the Daily Express reported.
Oakley was just 25 when she found fame as the star attraction in Buffalo Bill Cody's traveling 'Wild West' show.
Expert Tom Slater said that Oakley is remembered as an incredibly talented trick shooter.
He added that she was so popular that arguably she made Buffalo Bill's show famous, not the other way round.
