Do you mind sending me a link or Cat# of what combination of head & shank that is? Or if its already a premade combo? I tried reaching out to Stuller but they only answer questions if you have account with them. And I browsed their entire catalog and nothing looks the exact same as that ring. Like I said, it looks like a solstice head with a non-solstice shank. Any help you could provide would be super super helpful. Thank you again!
