I have a porcelain coach and horses that are paper stamped Lenwile Ardalt Artware Japan. This item has 24K chains that are the reins to the horses. The coach has a driver and a man and woman inside. The woman has an afghan on her lap with flowers that light up when the switch is on. The coach has a music box on the back. This item was purchased around 1978 or 1979. I would like to know what it is valued at.
