This is a two-tone stainless steel Onoto No. 7 nib unit in a broad point. It is an old-stock item. It has never been used, though I have tested it so it may have a trace of ink still in the feed. The No. 7 nib unit will fit the Magna range of pens and many other models. This is a nib unit that was made before the Chinese take-over of the company. I believe they were made by JoWo in Germany.
