The 1960s

 Right: The base of the paperweight.

Left: A paperweight made out of Ashburton marble. 7 cm in diameter, the date is unknown, but I am presuming that it was made in the mid to late 20th century.

Left: A salt and pepper shaker, probably made by Devonmoor, a company that existed briefly in 1913-14, and then from 1922 -1981.
'Blueware' with place names was one line produced from the 1950s.
The shakers belong to a  Milton family descendant now living in the United States - Jessie, née Milton, returned to Ashburton in the 1960s, and she may have taken them home with her at that time.
