I’ve been able to determine the hallmark on some of the jewelry I’m sifting through, but stumped on a few as I have limited resources at hand. So thanks so much for your help, and tolerance!!
for the DD, I’m going with Donald Douglas, Inlay Cuff – Garland's
If you have a fair amount of jewelry it might be worth it to invest in Hougarts book and check the art-Amerindien, tskies, and medicine man websites for starters. And hopefully someone here can ID something not in a reference.
Thanks 
I’ve checked the online sites, will need to order hougart. I’m almost done with this batch, but I know there is more lurking in my future.
Oh, I have a belt buckle with the DD on it. I believe mine is possibly Donald and Dorothy Clark.
I’m not sure about the Singer hallmark, I couldn’t find anything quite like that among his many marks on the Amerindian side, although it may not have every one if his hallmarks. I don’t have a good hallmark book either except a Hopi one).
Yes, i saw similar variations online, but not this exact one-
I’m pretty certain that was one of the variations that Tommy used.
Thank you! Purchased with that assumption, but there’s so much around his stuff.
Yes because his wife and family kept on after he passed. I can look at it and tell the difference.
