azimuthal projection
Azimuthal.
A projection of the graticule of the reduced earth onto a plane placed tangential to the reduced earth at a point. Depending on whether the point of tangency is the pole, the equator, or some other point, it is called polar, equatorial, or oblique azimuthal projection. Also called zenithal projection.

These would, of course, not have the properties of the azimuthal projections with similar names.
We are accustomed to think of azimuthal projections as circular in outline and thus, this map contradicts our preconception.
Obvious candidates for the spacing of the straight and parallel meridians is to take the radial values from the usual azimuthal projections and apply them to the spacing of the meridians.
In the computation of any azimuthal projection one needs a subroutine that calculates distance and direction from the map center.
An obvious thought is now to take a normal azimuthal projection and redraw it with meridians as equidistant, straight parallel lines as Craig did for his retro-azimuthal projection.
