Australian Watermark Inverted?

Question.....I have this stamp from Australia....14.5X14, A4 design with Watermark 9 INVERTED.....can not find a 14.5X14 with Wmk 9 in Scott's 2020 Classic Specialized 1840-1940. (there is a wmk 11 but no 9)
Anyone have a specialized Australian catalog that could possibly find a number for this??? I really like the inverted watermark...so its a keeper.

Its gonna be hard to see the Wmk, so I am gonna try and get another photo of it when I can jury rig a camera.




Here is the wmk picture rotated so the frontal image match's the gum side...the perfs match better so you can tell it is inverted.



OK, here is a better picture of the watermark itself......It's a Number 9 right?

I thought it was the sideways version to keep an eye out for...

There is that yes, but I think that's for the 1/2p green and 1p carmine stamps in the Kangaroo series....

The Scott catalog does a poor job differentiating between KGV perf varieties. The 2023 Scott catalog groups the 1p red with watermark 9 (single watermark) under Scott #21 and its suffixes, but it generalizes the perfs at 14. My 2023 Scott doesn't show a value for an inverted watermark, either.

A 2010 Stanley Gibbons catalog that I have access to lists your stamp as SG 21cw. SG 21c is the 1p carmine-red, die 1, watermark 9, with 14-1/4 by 14 comb perfs. SC 21cw is the same with an inverted watermark 9. The 2010 SG catalog values SG 21c at .60, and SG 21cw at 2.75.

Thank you Classic coins!! I'm still gonna keep it with my efo's.....!
