I have resealed it to the factory condition and repacked it like it looked in 1987. A few of the white pieces are slightly turning color. The trans-dark blue pieces are almost near-mint. The set appears to have been assembled until I did recently. To be honest (I forgot we had this in stock) it's been in storage since 2004.
I will include a video that shows monorail running perfectly and assembled with all pieces per the inventory provided by Bricklink and Lego website. The instructions are Very Fine to Near Mint. The backdrop cardboard is flawless! You will receive the TITA?? % guarantee which states all parts are period pieces and original to the set release.
Video will be provided shortly! Any question please feel free to ask. I have many other sets I'm listing as well.
No the base plates don't come with the monorail. You get just the parts that are laid out in the inventory photo.
The box repack photos will be next to be added. What can I say, this is still the best Lego Space set ever! It hadn't been put together since the late 80's and still works amazing!
I will be adding many more Light and Sound and other Classic space sets over next few weeks. Don't know the part or set number, just send me a pic and I'll help you out.
Have a pile of vintage Legoland space castle town 80's and don't know the sets or have the books or boxes, send me a photo and I'll let you know.
