Need help with this zuni hallmark

This hallmark is on the back of watch tips that once belonged to my grandfather. I’m hoping to identify the hallmark. I haven’t had any luck so far.

Thank you.

I couldn’t find anything, sorry. It is weird because you don’t think of many Zuni artists having a symbol for their mark. I keep trying to make this work for Elliot Qualo :). We think of this being Zuni, I have gone through a list of Hopi marks. It seems to have some age, you might be able to help with that. Good luck.

The inlay and design look like Frank Vacit to me.
