I have a used DUMBO Building Set that is in it's original box. It creates the Dumbo Flying Elephant after it is put together. It is similar to a type of Lego set. Email me if you are interested. It is the 1015 piece K'NEX Motorized Building Set. It currently sells for $150 plus $10 for shipping on Amazon. I am selling for one-third of the original price. The set should have all of the pieces , but I am not sure. It is in the original box. Email me if you are interested.
