K in a circle on a bracelet, I'm lost, please help

[WBANKS]

I have a bracelet marked with a bubble letter k or a sideways mushroom in a circle. Marked 925. I cant find anything on this. Can someone please help.

Thank you.

Could it possibly be a Sam Kramer , Its somewhat of a K and similar to his mushroom marking. It's possible he may have had different marks at different times because the mushroom is similar to his other known mark and the fact that its shaped like the very same mushroom in his initial K. I dont know it doesnt have the two bubbles above the circle but could it be?

wild guess: Mexican eagle mark.
