Vintage hammered metal ashtray. Incised mark: F. H. Banka Tinwerk. The island of Banka is an island of major mining operations. Not sure if this is hammered cast aluminum or pewter; it is heavy for its size. Some age/wear as expected from usage; age est: 1930's-40's. It is 4 inches wide x 1.25 tall. A neat collectible ashtray for the tobacciana collector! 2/15
