Evidence seems convincing... I'm calling it Loetz. Color combination is found in several other eexamples; acid stamp is a known stamp for Loetz: shape is a near match to a known Michael Powolny design (just missing ball between vase body and foot); signed as shown. H: 6 7/8".
If anyone can find a exact match on shape, I'd still love to see that reference.
