That's very interesting! My GB2 looked almost identical to yours my first time disassembling it. I couldn't get all of the pitting out, so I just patina'd the liners and standoffs to match my patina'd blade after getting all of the active rust off.GB2. Should have taken it apart much sooner. Needed some tlc. Added some Sharp Dressed Knives scales after the cleaning.
