    Fitz. If I may make a suggestion.
    Could you try do a bit of a polishing test on one of the pieces. It would help give some visual reference once the true material composition is identified.

    My thought is that they are as was suggested made out of pot metal. In which case it should retain the dull gray appearance when polished. Not the shiny appearance of polished aluminum.

    Hey, good idea. Maybe file a spot, sand another spot, polish a spot.

    Bay already sanded/polished one of the mating surfaces in an attempt to salvage one of them, and although smoother than the eroded surfaces, it isn't particularly shiny.

    It's been my experience with pot metal that you can get it VERY shiny, almost chrome-like, but it won't "hold" the shine.

    Any update on the material in question on these parts?

    Preliminary results are that they apparently contain no detectable aluminum (chemical reaction test) and a high percentage of zinc.

    I don't have any "official" results yet though.

    HEY EVERYONE! wikipedia has a real good article on the composition of "pot metal" after reading it you can see how vinegar could do this damage.
