> primitive stringed instruments with concave bows where the 'hair' contacts the string from below

I have seen pictures where the bow is held below the neck, so bow and hair are encircling the neck, but do you mean the hair is actually between the neck and string? that would mean stringing the bow each time, or I guess if left that way, you'd never lose your bow!

and milo, I only ever knew one of my grandparents, and I miss my Granny, too.
