Maker's mark and age help

I would appreciate any help in identifying the maker and age of these silver plated coasters please. Thanks in advance.

Have wondered if this silverplate mark was used by Manoah Rhodes & Sons Ltd. with (Thomas) Ackroyd Rhodes.
Would be interested to here others opinions.

I’m afraid it seems there was a similar unanswered query a couple of years ago …


Thanks for your replies. I’ll continue looking and let you know if I find anything. Cheers!
