The Flaws, errors, variations and anomalies of the WESTERN AUSTRALIA 1902 1d carmine, rose Watermark V over Crown, Perforation 12½ x 12.
by Ross Edwards
J.R.W. Purves in 1971 describe 6 consistent plate varieties Philately from Australia, December 1971 page 96.
In June 1972, in the same publication, he credits a friend Mr P. C. Pearson with the identification of an additional one which was subsequently identified by Murray Sherry.
Murray Sherry in an article in the Black Swan (September 1995, Vol 8, No 7) expands this list to 40 examples and provides both descriptions and illustrations of each.
I have regrouped the Purves, Pearson and Sherry examples into more defined areas on the stamp. These are;
OUTER FRAME LINE
INNER OCTAGONAL FRAME LINE
VERTICAL FLORAL PATTERNS
CORNER TRIANGULAR ORNAMENTS
WESTERN AUSTRALIA AND FRAME LINE
POSTAGE ONE PENNY AND FRAME LINE
No differentiation has been made between the colour shades as they were printed from the same plates.
Likewise no differentiation is made between watermarks, left, right, upright and upright inverted as these result solely from the direction the sheets were fed into the press and is not related to printing variations.
Variations, varieties and flaws can arise from a number of causes and can be divided in three groups.
PLATE FLAWS These are consistent and repeated examples arising from some deformation on the printing plate of which more than one example has been identified.
* including plate wear, cracks or scratches.
* Variations between stamps on the plate caused during the application transfer roller.
These are identified by being printed in bold type.
GROUP TWO consist of those which appear to be permanent malformations of the plate but have yet to be confirmed by 2 or more examples.
These are identified by being in normal type.
TRANSIGENT OR ONE OFF FLAWS
These include anomalies caused by dust or dirt on the plate, paper or in the ink or by paper movement during printing.
Some of these can be quite spectacular but are only temporary even if they are occasionally repeated.
These anomalies are printed in italics.
The Pale rose printing makes identification of varieties extremely difficult.
When examining a quantity of these stamps to find some of these flaws, I identified some additional examples.
The Purves, Pearson and Sherry examples are identified by their names in brackets.
The others are examples I have identified.
I look forward to comments, criticisms, corrections and additions to the following lists. Contact may be made directly by email or through the Society contact page.
