Here's a vintage model, a product from the early days of KATO (Kansui Kinzoku): a two-car set of the "Kani/Nahafu" carriages. The train marks for the Series 20 passenger cars were later changed to paper stickers, but when they first appeared, they came with plastic train marks. It's quite interesting. Please note that this product alone cannot form a complete train consist. Enjoy it as a vintage collection piece. It would also be a great addition to the KATO Museum's collection.
