These are undated but given their construction we feel they are from the 1930s. Each is a heavy metal hexagon with name of maker W&H on the back and each with a heavy vertical pin. Two pieces are in silvered brass with the first missing some silvering around the center raised area. Four others have a celluloid covered paper insert within the metal frame. The first four pieces designate “A” class while the last two designate “B” class. Minor wear on each but all are Fine to Exc. Paul Muchinsky Collection.
