HO Gauge Kumoha 12040 Operation has not been confirmed. As it is an old item, there is wear and paint剥げ (paint peeling) due to aging. Please judge from the photos. It was found while organizing my parents' house. According to my father, he seems to have purchased it about 40 years ago. He bought a completed model from a shop called Loco Model. It seems to be a rare item that is not often seen. I do not have knowledge of model trains, so I may not be able to answer questions. Please understand that this is an old item before purchasing. I don't know the market price because it's not widely available, so if you have a desired purchase price (excluding excessive ones), please comment.
