This unique set of ashtrays was made in the 1940s by the U.S. Naval Gun Factory. Each ashtray is made of chrome and is 4 inches in diameter with a very thick construction, making them durable and long-lasting. The design is simple yet elegant, making it a great addition to any collection of militaria items. These ashtrays are original period items from World War II (1939-45) and are a great way to own a piece of history.
