Claddagh marking(s) help?

[vivacie]

Hi, I recently bought this Claddagh ring from an estate sale (very old lady and daughter who both passed). I've been doing my best to research what the markings stand for, but I'm not finding any positive matches. I do know that is is 9K.
At first I thought it was quite old, but now I'm not so sure.

Any help would be greatly appreciated.

Here are all the markings inside the ring. Can take a picture of the ring itself if need be.

Hi,

Welcome to the Forum.

I can't help with the maker, but the ring was assayed at Dublin in 1987.
