> "According to legend, upon hearing of Colt's entrance into the lever-action rifle market, Winchester began to develop a prototype revolver to compete with Colt's market. A "gentleman's agreement" then followed between Colt and Winchester, with Colt agreeing to drop production of the Burgess and Winchester abandoning its plans to develop a revolver. The truth of this story has never been fully verified, and as such, the reason for the Burgess rifle's short production history is unknown.[1][4][5]"
