Mid Century Blown Art Glass Tripod Vase

Wondering who made this because I bought it thinking it to be Morgantown Glass. But upon consulting my collectors books later, no Morgantown pieces show the decorative ring around the neck or the same foot pattern. So I’m stumped; perhaps an independent glass blower? It’s 11” tall. The COLOR is amazing. I’ve never seen this unusual shade of smoky blue gray. Very striking! Love the tripod feet; not all that common, at least I can’t find many examples of tripod footed art glass. Interesting. WELCOME YOUR COMMENTS. Thanks!
