It came with a big parcel with second hand LEGO. It was mounted. So dad wanted to dismount it during holidays. But I wanted to participate building. So we dismounted it together. The bricks were washed and than we started the assembly.
The model has two instruction books. The first day I started from scratch, while dad started to build modules from the second book. The second day we changed and we terminated. So we could bring the model to Germany to show it to my grandparents.
