Is this a Petra teapot, what do you think?

This is being sold on Trade Me (20/10/22) as a Petra Teapot. Questions have been asked about how the seller can identify it as Petra.
They comment 'The glaze the feel the art work, no stamps cheers'
The base of the pot is painted and there is no stamp.
I have an extensive Petra collection and have never seen this paint design, style of t-pot or Petra painted on the base before.

Just wonder what others think?

I noticed that teapot when it was listed and couldn't place it as Petra's work.
Though the trader has a question mark in the listing so they are not really sure.
Traders only want to hear good news about their listings.
I would scroll on as the trader suggests.
