Updates to '50 Years of the Dinkie'
As new information becomes available, it has always been my intention to add any updates to the printed book here, so that it continues to reflect the current knowledge.
1 The Lumina Dinkies, pages 77-79 and 81
Masa Sunami (the acknowledged expert in Japanese vintage pens) has contacted me with some further information about the manufacturer of the Lumina Dinkie 570 pens.
He tells me that the Lumina materials were very popular in Japan at that time. He adds that the components for the ballpoint pens (mentioned on page 81) were found at the premises of the Kato Seisakusho Company in Osaka, which also indicates they were likely to have been the original manufacturer of the components for the Dinkie 570 pens and 54 pencils. The company was run by a colourful-sounding character named Kiyoshi Kato, and they are best known for the manufacture of their 'Spaceman' brand pens.
You can read more about the company and the exploits of Kiyoshi Kato in Masa's excellent book 'Fountain Pens of Japan', written with Andreas Lambrou,
2 A previously unknown No 20 Set box
Doug Wilson from Australia is the 'go to guy' when it comes to the history of Conway Stewart box sets. He recently sent me pictures of a previously unknown style of fancy card box for a No 20 set of the mid-late 1930s. This is very unusual for Conway Stewart as the lid is not the familiar hinged lid, but is a 'push-on' style, and it is completely removable. The provenance is good - the colour of the mid-late 1930s Dinkie 526 and Duropoint pencil match the colour of the case beautifully, and to avoid any doubt, there is a No 20 sticker on the underside of the box! It seems almost certain this was a style peculiar to the Australian market. A very few examples of similar style cases for other sets seem to have been recorded, but again, only within Australia.
3 An early blue candle flame 540
Conway Stewart enthusiast Bernard Prosser recently discovered the Dinkie 540 pictured below, a rare early example of the blue candle flame casein material. Given the metal ring fitment on the cap-top and the bandless cap, the pen dates from c1933. The material is identified in the colour swatches as MA-52-54-02, however this discovery places it nearly 20 years earlier than the implied 1952 introduction date, around the same time as the red candle flame MA-34-54-01. Unfortunately it is not easy to change the captions in the image files, so I have added a note of explanation to the foot of the Marble colour swatches page.
