Little is known about him!
His mark you can find on small objects of high quality - miniature eastereggs, frames and objets d´art in gold, silver and enamel.
Question: Does somebody know more about him? I am very interested on further informations!
Here are the pics:

mark

a miniature easteregg (red cross egg), worn by the ladies of the court during WW I when visiting "selected " wounded soldiers in hospitals

Any help very welcome!
