Vintage Wooden Pen, Antique Pen, Ink Pen, Dip Pen, Showa Retro

Old wooden pen. I'm not sure of the exact age, but it's quite old. It has a wooden handle with NO 300 engraved on it. I think it's a cool, stylish pen. The nib is old deadstock, but it has been replaced with a new one. The total length of the handle part is approximately 18.2 cm. There are scuffs, scratches, dirt, and signs of age, but I think it has a good atmosphere. Thank you to those who understand old items.
