Sterling overlay orange vase, Czech?

I have had this vase for a few years picked it up at a rummie (garage sale). I don't remember what I paid but I doubt it was more then a dollar. My pictures are bad but the image is a hunter on horse back with his dogs. It is signed Sterling in the image. The top seems like it should have had something on it? I am wondering if this may be Czech? Any thoughts or comments welcome. Thanks for looking.
