Need help identifying artist on belt buckle

This belonged to my husband that passed away in 2005. He had it made while in either Arizona or New Mexico when he was a teenager. It holds a operating mini NAA revolver. It has two markings on it. One on the inside under the pistol and one on the back. I was wondering if anyone knew who the artist is and also approximate value. I know the pistol retail is $230. Thank you for any help you can offer.

This is a very cool piece. The closest mark I can find in a book is Daisy Hooee. She is the mother of Shirley Benn and I don’t know if she would have ever done work like this. I want to say I have seen this style before, and believe it to be Native American made. Thanks for sharing.
