It is a Kabaya model kit from Japan made in the 1980's. They were sold in Japan packaged with chocolate candy. Because they were so inexpensive, they were mostly considered a throw away item. They are quite rare even in Japan these days. I got mine through a person that had connections in Japan. To get one will be really hard, to get a couple is going to be very taxing indeed. They don't even show up on ebay often.
