In the days before legendary robbers such as "Pretty Boy" Floyd, Bonnie and Clyde and even John Dillinger, the "Black and White Bandits" were on the loose, terrorizing banks across Southern California.  They got more than they bargained for when they came to San Diego.  Behind the work of Detective Sergeant Maurice "Mike" Shea, the robbers were arrested but not after a gunfight.  As a token of their bravery, Chief of Detectives Paul J. Hayes Sr. presented this .45 caliber revolver, Smith and Wesson 1917, to the sergeant. Note the ornate engraving on both sides of the gun.
