ID potter for a tiny jug? FR mark

Hi, I wonder if anyone can identify this very elaborate mark on a very tiny jug! I think it’s an intertwined P and A, or maybe R?

Any suggestions appreciated.

I believe it's an entwined FR / RF.
I've come across a few pieces. They look 1970s in date. Often misattributed to Anne Rennie who has a similar Font for her AR stamp, but not her style of work, so still a mystery

You’re right - it’s FR, now you say it, it’s clear! I’ll do a bit more digging now I have some definite initials to work with. Thank you!

Sometimes things take years to be identified on here, so it's worth coming back........................... especially as Naomi has an encyclopedic knowledge of obscure British studio pottery marks.

P.S. She didn't pay me to write that ............. (not yet anyway).
