This is a ballpoint pen that Pelikan sold as a matching pen for their "500" series fountain pens between 1955 and 1963. The gray barrel is a rare specification only seen in the later models, making this a very unusual color. There are no engravings or dents, and it's in remarkably good condition, considering it's a 70-year-old ballpoint pen. The pen has been tested and is working, and it is fitted with a Schneider 700M refill. I believe I paid around 30,000 yen for it when I purchased it, so I'm selling it at a slightly reduced price.
