(AP) — A gun thought to have been carried by Wyatt Earp during the famous O.K. Corral shootout in Tombstone has sold for $225,000.

A telephone bidder in New Mexico made the winning bid for the Colt .45 revolver Thursday night.

J. Levine Auction & Appraisal officials say an auction of numerous items related to Earp and his family in Scottsdale, Ariz., brought in more than $445,000.

The auction house initially valued the Colt between $100,000 and $150,000.

The items belonged to the estate of Glenn Boyer, an author of several books on Earp. Boyer died in February 2013.

Some have questioned the items’ authenticity while others say Boyer was a credible researcher.

A Chandler man spent $150,000 on a shotgun owned by Earp, a family archive and other items.
