Gift of the Mechanicus

The Gift of the Mechanicus was an event that occurred in the history of the Midnight Claws Space Marine Chapter, when they managed to acquire several rhino armoured personnel carriers, quite by accident, as they were meant for another Chapter with a similar name. Being an honourable Chapter, the Midnight Claws attempted to seek out and bring these vehicles to whom they were intended for. This quest would take the Chapter nearly two centuries, until both Chapters happened to make one another's acquaintance sheerly by happenstance. In gratitude, the Midnight Claws' cousin-Chapter gifted them with a surplus of their Stalker-pattern bolters.

History
The Chapter acquired several rhinos from the Adeptus Mechanicus by accident. Instead those being needed by a chapter of a similar name. The chapter would attempt to track and find the other Chapter until 812.M41. One century after giving up the two chapters meet each other by accident. The Midnight Claws would give the Rhinos to the designated chapter. In return, they received a stash of coveted Stalker pattern bolters that were in surplus.
