Vintage Aurora 88 Nib Sizes

[jonlr]

Does any one know what the various markings on the blind caps of vintage Aurora 88 indicate in regards to nib width, flex? I have pens with a circle, a dot, a dot within a circle marked on the blind cap base. Thanks for your help. You may respond directly to jonr529@aol.com

Just to add to the confusion, I heard that the color of the cap tip indicates the nib size. My hooded 88 has a silver color cap tip. On the blind cap there is a countersunk round hole, forming a ring. Within the hole there is a second smaller ring. This pen draws a 0.22 to 0.25 mm line width - which is EF even by Japanese standards.

I thought sanpei (Paolo) would know, but then I found this:

It took me a while, and I know this is an old thread, but I found this colour code chart:

And....color code?

Copy the picture then expand it. Across the top it translates as "flexible, medium, hard" and down the left as "fine, medium, broad".

 

The symbols are, a dot for fine or dot in a circle for broad, with just a circle for medium. Colours are green for flexible, white for medium, red for hard.
