    Do you make/resilver mirrors yourself?
    I am currently shopping for an old vernier sextant,
    mostly paying attention on the state of the arc,
    frame, vernier and filters.
    The requirement that mirrors should be also in good condition
    substantially narrows my choice. So I thought of trying to
    learn how to resilver mirrors myself.
    Can you give any advise on this?
    I have in mind a recipe from an old navigation book
    which requires mercury and tin foil.
