Very rare yellow Kosuge puzzle car with original box. It seems to be missing it’s key. Toy is in very good condition. Box is good also but I’m not exactly sure how it fits together so it’s a bit loosey goosey at the moment. Untested but assumed to be working. All other wind up toys in the lot this one came in we’re working. Please examine photos carefully. When these turn up, which is rare, it’s usually the red version. The yellow car seems to be much rarer. With box they sell for $300-$500 it looks like. Ships ASAP! Thanks
