Here is the first Lucasfilm Ltd. licensed Star Wars Obi-Wan Kenobi lightsaber (#01 of an intended 10,000) ever produced, authorized, approved and licensed by Lucasfilm Ltd.
I would assume that the photo above is a test photo once the #01 saber was completed to size the plexiglas case and plaque etc.
Those schematics were for the company that produced the outsourced parts for the saber.
