The original M815, the Wall Street Limited Edition not the recent Metal Striped Special Edition. It features a dark grey rather than black cap and a grey marbled barrel with a 24K gold plaque embedded in it to mirror those on the doors in Wall Street, otherwise this pen is pretty standard.
This is another of my older M800 two tone fine nibs that are actually fine. It writes like a modern Pelikan extra fine. It is a very nice flowing smooth nib.
Sometimes an ink can be unlucky and get inked up with a fine nib when it really needs a broad nib to show its true colours. This is the case with Noodler’s FPN Van Gogh Starry Night Blue. This ink looks black on the writing sample scans but in reality it is a very dark blue-black. Oh well maybe in three years this ink will score a broad stub.
