| | |   Chrome plated zinc ashtray. This lovely chrome plated ashtray is probably made of an alloy that is primarily zinc, but I'm only guessing at the percentage.  The lettering around the center says St. Louis Die Casting Corp, Aluminum Zinc Magnesium.  It's too heavy to be aluminum or magnesium, which leaves zinc, or one of the inexpensive pot metal alloys that are based on it.
