onway Stewart, started to produce miniature pens called Dinkies in the early 1920's, and production in different shapes and colours continued until the 1960's. Many of the most beautiful dinkies were made in the 30's from casein and belong to this early series. However, casein pens can become badly crased under prolonged exposure to light and the condition of many surviving pens is compromised.
he pens in this circle and their matching pencils (Duro-point 2), show a range of different designs that I have catalogued in my "book" of numbers where you can see full size images. Some of these sets belong to pouches that can be seen in my "highlights" section.
