The standards of quality for W&N's most renowned line of kolinsky sable brush, the Series 7, began after Queen Victoria ordered it should be "the very finest watercolour brush" in 1866. A few months before his death, Henry Newton sold the business to the newly incorporated firm of "Winsor & Newton Ltd.", which included members of both families amongst the shareholders. In 1937, W&N introduced its gouache paints.
