Hello again, Frank,
A quick postscript to my first answer ... I can also get my 4 sub-dials
by using parallelograms arranged in NS planes at the sides of the dial
face, and sitting on the horizontal dial surface. The skew of the
parallelograms would be such that they provide polar styles, so that
each provides one overshot and one undershot style. This arrangement is
using two gnomons though - like the Troschel dial - so is really two
separate dials drawn with overlapping dial faces, hence it doesn't
conform to the "all in the noon gap" requirement.
