RAF PRAYER unknown marks . Help requested

I am trying to help identify the maker of an item with these marks. I don’t think they are UK silver hall marks but I may be wrong. It is on the reverse of a small silver plaque given to a mother whose son while serving in the Royal Air force. Any advice welcome as we are trying to identify the maker to order more. Many thanks in advance.

These are pewter marks, not silver marks. The maker was A E Williams: https://www.aewilliamspewter.com/


thank you. I had done some searching earlier after I posted here, and came to the same conclusion, but it’s good to know you confirmed my findings.
