Blue Vase Stoneware(?)

Hello!

I found this vase and loved the color and shape unfortunately I cant find much more about it. The foot gives it some age (or maybe its just the color of the clay?), I was hoping someone could give me some more information concerning it so I can continue my research. Unfortunately I feel the bottom numbers are probably shape/design/glaze code. What would you term this technique (/style?) of glaze? Thank you for your help!

I'm wondering if it's California Pottery.

I should have included this angle of the vase as I now believe its probably meant to be a spittoon if that helps identify it further.



I actually got the idea from seeing another spittoon this weekend and the curved lip along the opening (I assume to prevent spilling) which this piece features. It  could be from California as well, Ive found a few pieces of Californian pottery (proximity wise it makes sense).

Possibly a spittoon, but the inner lip maybe for a wire mesh insert to help with flower arranging.

I don't think it is, but it reminds me of Fiesta Ware.
