Help identifying mark on unique concho belt

I’m a newbie hoping to find information about the maker of my late stepmother’s concho belt. She lived in Santa Fe NM for many decades and had a nice collection of Native American jewelry. I haven’t been able to identify this mark or find a similar belt and will be most grateful for any thoughts on the maker.

This is a very beautiful belt, and I have never seen one which it resembles. I have a strong feeling it is of fairly recent make. I could not find anything in HALLMARKS OF THE SOUTHWEST.

Thank you for checking! My dad tells me they bought the belt in the last 20 years, so yes, it is not terribly old. He just doesn’t remember the details of the purchase or the maker. Thank you for trying!
