Weird ring hallmark help please

[rykroll]

Anyone know anything about this hallmark in this old ring I found?

Perhaps James Avery jewelery

I compared James Avery hallmarks I couldn't find a match I think the ring is at least a low carrot gold

Due to the look, it's just gold plated. (I think)

Can you write down what the letters are or design and post a picture. It could be gold, I have some that comes up stained sometimes.

It just has to be cleaned I know it's not the prettiest ring but it's one of my best thank you!
