Crystal Steuben Dish

Trying to figure what’s the dish used for and who was the designer.
Thanks

 

I believe this is considered a nut dish. By designer are you referring to the influence? Is it signed Steuben?

 

Is it signed?

 

or olive dish....

 

I got these pieces and they are all signed. By designer I mean who actually designed it.
If not wrong, the four feet bowl was designed by John Dreves and the ashtray by George Thompson.
The piece I’m asking has a spout but probably just decorative as the double scrolls that can be used as a handle are underneath the spout. Or maybe they are also just part of the design.

 

It may have had a use name, Nut Dish, Olive Dish, whatever, but it was sold to be decorative.
