9/11 Revolver - Officer Walter Weaver
This stainless steel revolver was recovered from the World Trade Center ruins at Ground Zero. It was carried by New York police officer Walter Weaver on September 11, 2001. Officer Weaver, like many fellow officers and firemen that day, rushed into the Twin Towers to save victims trapped inside. 223rd Street in the Bronx has been renamed to honor Officer Walter Weaver.
