This is the real LEGO TECHNIK 8880. It is pretty rare and may be the only one currently for sale that uses the black version of part 6542 as the listings I saw use this piece in dark gray! I remember getting this as a Christmas present growing up in Germany, back in 1998. It's been in a glass display since.

Great set with printed stickers.  As far as I can remember, it is complete since after assembly, it went straight into the glass display my grandfather got me and hasnt left until the photos I just took. Practically zero dust after 25+ years of good storage. Comes with everything you see. Selling as is, so please carefully review the photos before purchasing.
