Brutalist pottery makers ID

One of my game plans when hunting is that ugly is often overlooked. These are definitely in that category. Whether I should have overlooked them is up for debate….
I picked up the first of these pots and saw the Rooke stamp which very vaguely rang a bell with me so for £3 it’s mine. Then I saw there was a small collection of similar Cornish style brutalist pottery so I scooped it all up.
The lady in the shop genuinely asked me why on earth I wanted them and they are currently stashed in the car as OH will go nuts if I bring back more junk. The first I’ve identified at Bernard Rooke, the second is Tamar Pottery but the pair of slab pots with a duck and a saint/king(?) back stamps are eluding me.
Just to show I’ve done my due diligence, you can see what Google Lens thought of my purchase
Any ideas please on the slab pots?
Thankyou

Unidentified!

Google Lens result at its finest!

 

Nice bit of Rooke that.

I’m wondering if the slabs are not from the U.K., tbh. Although, the mark is vaguely familiar.
