HI, I will go through my Steuben line drawings again, but I do not think I missed the shape... They are absolutely gorgeous pieces which I love, but I am currently of the opinion, at the moment, that they are not Steuben....
I will let you know either way about locating the shape in the drawings or not...
They have a Steubenesque feel to them, so the suggestion of Stevens & Williams would be a strong contender in my book...
