Section

The skew of the arms if any is very slight and warping should
possibly be taken into account, but what little there is suggests
that it is of  the return-boomerang type - i.e. B and D above the
plane running through the centre, and A and E below it. The ends
A, B and D, E. are curved above the plane at centre C.
