This is an assembly kit for a Japanese-made HO gauge steam locomotive, manufactured and sold during the Showa era. This product is mainly composed of brass parts and is a full-fledged kit designed for advanced modelers of the time. The included assembly instructions are original blueprints, known as "blueprints," and are a very valuable resource for understanding the structure and design philosophy. While the manufacturer's name is not confirmed, based on the structure and design, it is believed to be a craftsman-made kit from the early days of Japanese HO gauge in the 1950s and 60s. Similar kits are rare nowadays, and this item is highly collectible, especially with the included documentation. 【Condition】 ・The parts appear to be unassembled. ・The paper items show signs of aging, such as yellowing, stains, and folds. ・Metal parts show signs of aging, such as dullness. ・Sold as is. ・Not all parts have been inspected.
