Help identify hallmark

Hi. I just found this ring in a box and am wondering what the hallmark means and if anyone can tell me anything else about it. Thank you!

Hello, thanks for sharing. There is a group of brothers in Crownpoint that make pieces like this. The last name is Perry. I know Martin Perry and his work looks very similar to this. His current hallmark is different than this https://www.etsy.com/listing/272991616/vintage-navajo-martin-perry-sterling, but it could have been this before. If I see him I will ask.
