Platon Fountain Pen, Fine Nib

This is a product from the now-defunct Japanese fountain pen manufacturer, Platon Fountain Pen.

Unusually for an old Japanese fountain pen, it's a piston-filling type with a barrel that has an ink window. The piston smoothly draws ink, and the ink view is very clear. The photo shows a small amount of red ink inside.

The nib is steel, and the line width is a Japanese F. It can write quite fine lines.

Considering its age, I've marked it as "slightly scratched." However, although there is some clouding on the clip's metal, I think it's in good condition overall for its age.
