STIHL Short block Assembly: has parts 41400212500, 41400210300, flywheel, clutch.
The item pictured is what you will receive.
This came from an engine that was not running.  I took it apart and could not find any visible defects.
The piston and rings, flywheel, and clutch all look good but I cannot attest to their functionality.
