Manufactured from 1926 to 1941. As stated in the accompanying 2010 dated and signed letter of provenance on Collector Firearms letterhead, this revolver belonged to United States Secret Service Agent Michael Levis who was assigned President Franklin Roosevelt's detail. The letter is written by Levis' grandson. The revolver remained in the family until Levis' grandson parted with it in 2010. Included is a picture of Agent Levis walking along side the presidential motorcade with President Roosevelt and First Lady Eleanor Roosevelt. Roosevelt served as the 32nd president of the United States from 1933 until his death in 1945, guiding America through the Great Depression and World War II. It was Levis' duty to protect the president who, in 1933 as President-elect, had been targeted in a failed an assassination attempt. As a wartime president Roosevelt received greater protection by becoming the first U.S. President to travel in an armored vehicle, which once belonged to infamous gangster Al Capone. The revolver is fitted with the rare short 4 inch barrel as the standard length was 6 1/2 inches. These short barrel lengths were preferred by law enforcement agencies. Matching serial numbers appear on the butt, cylinder, and ejector shroud. The revolver wears a set of stag grips. Provenance: Secret Service Agent Michael Levis; The Levis Family; Property of a Gentleman
