    Toothpaste is indeed a very good, fine polish.  That sounds like a
    good solution to an annoying problem.

    The Freiberger I referred to was pretty tired and the problems came
    mainly from a combination of wear and neglect.  The Yachtsman,
    however, strikes me as a very no-frills instrument with limited filter
    options and a micrometer that seemed overly difficult to read.  Not
    having used the larger models, I have no direct information on them.
    Thanks for the URL to check Freibergers out.
