hi David - sorry, regret to say I'm clueless as to origin, but in view of the finish on the base then wouldn't have thought Czechoslovakian, and don't think they've been into this type of design. You may have already tried searching under the description of 'thorn vase', but that's the appearance this one has - a design that goes back into the C19, and still surfaces occasionally. Fingers crossed others here will recognize your vase.
