The 1937 Coronation Stamp of King George VI: Cylinder 19
IntroductionCylinder 19, An Introduction but no Analysis
This appears to be a very scarce cylinder indeed. During the 45 years that material has been collected, not a single whole pane has been found and so a substantiated analysis has been impossible. However, a small set of cylinder blocks and a few odd pieces show that this is a cylinder well worthy of comparative analysis. For example, there are two flaws of exhibition quality; the beetle flaw in the E of the monogramme, and the mysterious "hatch patch", both listed in the sample flaws in the Stanley Gibbons Great Britain Specialized Catalogue Vol. 2. for the Four Kings. There is a simlar hatch patch flaw on cylinder 30, not listed in SG.
There is an anomaly with a constant, but ever changing flaw on the Queen's jaw that appears on both panes. On the no stop pane there is sufficient material to demonstrate the progressive nature of the flaw. On the stop pane there is insufficient material to know whether the Queen's jaw flaw (the dreaded lurgy) is constant and also progressive.
Separating the first printing from the second is easy; the cylinder shows that the Ray Flaw was unretouched before use but it was clearly retouched for the second printing. The first printing is given two states here based on an apparent difference between Ray Flaws.
The lack of any whole plates or panes leaves a significant opportunity to contribute to philatelic knowledge and hopefully somebody is able to step in here.
