Very nice. Would you clarify what is meant by "without the pip perforation" in your description? I'd like to see what the "normal" corner would look like. Thanks.

Hi Peter
A pip is a perforation guide mark to ensure accurate centring of perforations; markings were placed in the margins of sheets. These marks identified pinning points where the sheets were secured prior to passing through the perforating machine.
Here is the same type of stamps with the "pip" in bottom centre of the selvedge (orange circle over a pin hole), the block of 4 is the late plate crack of this particular variety where the crack is under the imprint (very scarce).

A rare lower left corner block of 4 1938 ½d Kangaroo. Perforation 13½ x 14. Very early state of cracked plate below W.C.G. McCracken imprint without the pip perforation. This is the only example identified to date.
