bowl with applied decoration

Help Please! Found this pottery bowl. 19.5cm diameter. Love the decoration and colour tonings (second photo accurate colour). Decoration applied in overlapping  almost scalloped pattern and sort of scored to give ridged effect-perhaps meant to be flowers (kowhai?) or leaves?? Obviously by an accomplished hand. Have been unable to identify mark on base, or even which way around it is (maybe last photo?).  Any suggestions appreciated thanks.

Yes I think the last photo is the right way up, but what does it show?
Perhaps a B and a g?

Yes a P & g, or maybe even a P and B ?

could we have a larger photo of just the mark? I struggle to see marks clearly enough in composite pictures

Sure. This photo shows just camera image.

This photo shows same mark under magnification-which gives clearer indication of more flowing approach to first part of mark (J?)-the rest just seems jumbled.

It does remind me of Jackie hayward's mark, but not at all sure on that

Unfamiliar with Jackie Hayward-can't find her mark on this site-more info welcomed if this is a possibility, thanks

This is her mark from nzpotters.com
