wiener wekstatte designer markings

[rob h]

I have a silver hatpin marked with the wiener werkstatte marking. We are trying to identify the other markings . There is another mark above the pin shaft but we can only post 2 photos.

Hello and congrats. The mark on the left is what’s left of the designer’s monogram: JH ligated for Josef Hoffmann. The mark on the right hand side is the mark of the metalsmith who executed this: Josef Holi. Best wishes, Bahner

Under the a 5x magnifying glass most of the hoffmann mongram is visible.
