**TOMIX 100 Series Small Window Prototype - Rare Model!** This product is a phantom prototype model that was sold for a very short period. The model faithfully replicates the prototype of the actual train, but when the mass-produced version appeared, the windows were enlarged. The model's mold was then modified and re-released as the mass-produced version. As a result, this small-window specification was discontinued in a short period, making it a rare item today. The biggest features of this prototype are the **small window specification** and the **red "NS mark" painted on the double-decker cars**. The NS mark is a design of the initials "New Shinkansen" and was a special symbol only for the prototype era. With the privatization of Japanese National Railways in 1987, the logo was replaced with the JR logo in the mass-produced version, making this prototype with the NS mark a very valuable item. ↓ I am also listing other rare railway models! #1O1O House_Railway Models **Condition** ・Operation and lights are problem-free. ・The exterior is relatively clean without yellowing (commensurate with age). **Included Items** ・All items shown in the images. **Notes** ・Please understand that this is a used item before purchasing. ・Returns are not accepted to prevent replacement issues.
