Anyone recognize this mark!

I am new to this forum and don’t have many silver pieces. I found this in my mom’s jewelry box and was wondering if it a Lee Charley piece. I can probably take beter pictures if needed. At first I thought it was LO but then realized the O was not completelt closed and few other online friends saw a C as well. I can’t find many of his pieces online so I ant really compare it to his work.

Doesn’t look like the pictures loaded here is a link to them.

I was waiting until I saw Lee, his hallmark is like this, but he says he did not make this.
