"Bureau of Aeronautics United States Navy" and produced in 1940, before the U.S. entry into "the big one" came a year later. What a great item, Fred. Thanks to both you and your dad for sharing it with us. That dial is so cool, Lindell | |||

Fred, I'm a little confused. While Swiss coin silver cases were often, but not always, 0.800 fine (that is, 800 parts pure silver, alloyed with 200 parts base metals), American coin silver is 0.900 fine, the same composition as U.S. silver coins minted before 1964. Since the case is made by Keystone, what are the exact markings in the inside of the case back? Did Keystone make these cases with a lower silver content than normal civilian cases, possibly because of wartime needs? Ed Ueberall IHC Member 34 The Escapement | |||
