Pelikan M400 NOS

Pelikan M400 NOS, with a sticker. The pen comes, I think, from the late 80’s (imprint on the cap says W-Germany), has never been inked (I dipped it only for a writing sample – M nib with some flex) and still has a sticker on. It is engraved. I haven’t done any restoration work, it is as I got it, and looks as if was released from the factory yesterday.
