    I recently cleaned a bunch of rusted screwdriver bits by soaking in cola overnight. They only needed a mild brushing with steel wool after that. If I was trying any other restoration work on metal I would use it again. I often restore knives and tools so the cola is a real time saver.

    Great pictures! You may have cleaned it to much, by removing the patina you have removed much of the value but knife collectors will still go wild over it.
     I hope this translates properly
