A great piece of American WW-II and Cold War Military and Navy History!!  The ACTUAL Reed & Barton Sterling Silver Presentation Bowl given to the wife of Rear Admiral John Allison Fitzgerald when she Christened the USS Grenadier SS-525 Submarine in Boston on February 10, 1951!!  This piece of history weighs 950+/- grams (the real value, as you know, is not the silver content) and measures 10" in diameter and approximately 5" tall.  

The USS Grenadier was launched on December 15, 1944, at the Boston Naval Shipyard and Commissioned on February 10, 1951.  Most noteworthy though, is its presence at the Bay of Pigs Incident in Cuba during the Cuban Missile Crisis in 1962.
