This is the only kit sold in 2003. It isn't a new playset but is a collection of sets that were previously sold all bundled up in one purchase. The focus of this kit is the Hogwarts castle.
I have never seen this kit listed on either Amazon or eBay but I’ve included links to both sources just in case you get lucky. However, it will be much easier for you to buy the sets that were included in this kit separately, which is why I’ve included links to each set in the description.
