Australia 3RD Wmk 1 Shilling Kangaroo - Catalogue Number?

Does anyone have a catalogue number for the grey 1 shilling kangaroo (3rd wmk)? It's not listed in my Gibbons, but perhaps it's in the new ACSC, which I don't own as yet.

I think it is a faded blue-green SG40. There was no grey 1/- kangaroo. If you look at the bottom left corner you can see a suggestion of blue-green.

In real life, so to speak, the stamp is grey all over, with darker grey in the southwest corner. I don't know why the scan makes it look bluish. Either way, how would blue-green fade to grey? Wouldn't it fade to a paler shade of blue-green (I've seen a few examples of that)?

Haven't been around much of late so sorry for the late reply ;)

As 22crows said, the 1/- Kangaroo was only issued in shades of emerald & blue-green. There is a shade of grey-green listed in ACSC which is rarer than the other shades, but yours certainly appears to be faded, so impossible to tell what shade it is from the scan.

Thanks for the comment, MmmmmBalf, but I find it difficult to believe that the emerald-green 'roo just happened to fade to the exact some colour as the one pound roo. It's the same colour (grey), exactly, although somewhat darker (and just slightly bluer) in the bottom lefthand corner.

jimjamtwo - Far be it from me to syle myself as an expert, but the coloration of your stamp is rather curious. The lower left corner is blueish (with the faintest hints of greenish?). The lower center of the stamp (under the Roo) is brownish grey (did he have a mess?). The upper half is indeed grey, but of varying intensity. This leads me (and might perhaps also lead the average collector) to think that the current appearance was not the appearance it had when it was printed.

With the variable color on the face, and the fact that it has been soaked (at least), we can't possibly determine where that one started out.

The bottom-left corner leads me to guess that it started out life as a blue-green stamp.
