The 1937 Coronation Stamp of King George VI: Cylinder 23
IntroductionA Study of Cylinder 23 together with a miscellany of Accidentals and Constant Flaws
This is a comparatively easy cylinder to study but as usual, the output from the first printing far exceeds subsequent production.
It seems there were three printings, treated here as three states. The first printing seems to have at least three states, but the differences are minuscule and uncertain. Several whole panes were collected. There are many good constant flaws, the most noteworthy is the bold hatching in the Lacing on the no-stop pane. The line in the number one flaw was once listed as not being constant, then changed to be only in a later printing but is in fact fully constant. At another extreme, a ghost of the multipositive Tennis Ball flaw found only on early cylinders is just where it shouldn't be !
A dozen or so flaws on the stop pane echo the left side and once again support the three distinct printings conclusion, partly by some flaws being constant only for a particular state. The miscellany of pages after the analysis demonstrate how knowledge of the constant flaws can be used to diagnose different states and also identify otherwise anonymous pieces.
