You asked what are the scales' markings on the printed Kavrayskiy's grid.
The printed grid has:
- the equatorial line marked (right-to-left) 0°~180° as a lower string; then 180°~360° (left-to-right) as an upper string. The right-hand end of the equatorial line has the label "N" (near the 0° | 360° mark), the left-hand end has the label "S" (near the 180° mark);
- the upper pole has the "PN" label, the lower pole has the "PS" label;
- the outer circle has just two marked arcs: 0°~90° - from each end of the equatorial line to either pole (i.e from the "S" to "PN", named the "Northen declination", and from the "N" to "PS", named the "Southern declination").
Also there is a sketch showing the proper usage of the grid, I'd better scan it and post it here.
Hope that helps.
