|LEGO → System → Castle → Black Knights|
- The set is identical to 2890 King's Catapult, which was released as Promotional set in Japan in 1998.
- This is one of only two catapults of the Black Knights line, the other one being 1491 Dual Defender from 1992.
- Oddly, the set's name suggests that it's attributed to a king, a fact that would usually refer to a Crusaders set.
- It was also included in 1900 Castle Space Special Bonus Set.
