RAINBOW 202 cap, and there is an engraving inside. I believe it's a product from over 40 years ago, but the details are unknown. The nib, barrel, and cap each have small scratches, rust, etc. Please check the photos. It's a type that uses ink by suction, and when you remove the barrel, there is a plunger for ink suction. However, the bag-like ink reservoir inside is missing, and it's unusable as is. This is being sold as junk. The coaster and small plate shown in the photos are for photography purposes. They are not included.
