       Name: SHIP_COBRA_MK_3_P
       Type: Variable
   Category: Drawing ships
    Summary: Ship blueprint for a Cobra Mk III (pirate)
  Deep dive: Ship blueprints

Code variation 1 of 5A variation in the comments only

This variation is blank in the Disc (flight) and 6502 Second Processor versions.

Master
 The ship blueprint for the pirate Cobra Mk III reuses the edges and faces data
 from the non-pirate Cobra Mk III, so the edges and faces data offsets are
 negative.
