Thank you for viewing. This is a N gauge KATO DD51. It was displayed as part of my grandfather's collection. When I received it from my grandfather, he said he had checked its operation, but I do not have the environment to test its operation at home, so I have not been able to confirm its operation. It has been on display for a long time, so there may be missing parts. Please check the images. Please understand that this is a used item, and only those who agree with the above after checking the images should purchase. I am not familiar with N gauge, so please understand that I may not be able to answer detailed questions. Please ask any questions before purchasing. Please note that we cannot reserve items to prevent trouble. Shipping will be packed with bubble wrap and will be sent via Yu-Packet Plus of Yu-Yu Mercari.
