Raku pottery .p. or .DP. mark.

Good evening,
I recently bought these two pots at auction.
I’ve looked at Guy Perkins & Pip, mark is similar but not right and can’t find any similar pottery they have produced.
I noted their mark did change but it’s the difference in the range of pots which put me off.
It could be from abroad and if no one recognises the style then that’s probably where I try next..
I’ve shown both pots because I thought the fish depiction might jog someone’s memory.
Grateful for any assistance or suggestions where to research.
Kind regards

Same mark different angles!
