I had a look through my 1/2d kangaroos and found three candidates which look quite similar. After a quick look at the WIKI, I`m not yet really sure which positions they are, as I`ve seen 1R36 is also a flaw which looks quite similar to 1R6 and 1R40. Here are the three examples!
1. example: (I can`t see a watermark line, the watermark is shifted low, so I can exclude 1R6 as position)
2. example: (I can`t see a watermark line, the watermark is shifted high, so it could be 1R6 as well as 1R40 or 1R36)
3. example: (there is a vertical watermark line to the left, when seen from back, so it could be 1R6 or 1R36, I can exclude 1R40)
Any suggestions would be great! I hope I could contribute something to the mystery!?
Thanks for this josto,
You are right there are three positions where there is a coloured flaw off the NSW coast in roughly the same position. Those positions are 1R6 (already discussed), 1R36 and 1R40. Go to the WIKI to get illustrations of all three flaws.
Stamps from the three positions have different watermark border lines and different secondary flaw markers.
1R6 has a top and RH watermark line from the front (assuming the lines are in their correct positions)
1R36 has a RH watermark line from the front (assuming the line is in its correct position)
1R40 has no watermark line
According to the Pope monograph, the key secondary markers are:
Break in 2nd shading line above last A of AUSTRALIA and in later printings a notch in upper frame above US of AUSTRALIA. In late printings there is also a white area between feet of last A of AUSTRALIA joined to crossbar above.
Coloured flaw joining apex of inner frame to lower outer frame below it.
It would seem therefore that your first stamp is 1R40, with no watermark line and no secondary marker. The second stamp is probably 1R36, with the coloured flaw in the apex, while the third stamp appears also to be 1R36 with both the apex flaw and the watermark line.
