Well...I found him, but it was from a separate clue I stumbled accross. I guess I was interpreting the first clue wrong.
The name of the base I found him on has letters that are not in the ship name, loot name, or either ship type name (since the ship in the info and what you see in space differ I tried it with both). Actually I'm not sure what the connection is.
The clue I used to find him is a news item on a base close to the first clue, but in a different system :}. As I said, I just stumbled accross this while base-hopping after giving up on a cerebral solution (I had even tried all the bases where he might have obtained his "loot"
.
Giskard, if you see this, please forgive me if I'm giving too much away. Also please give me a hint if I missed something and should go back to the first clue.
