Unfortunately, from the time before 1781 no punctual plates are handed over, so I can not help you with your master's mark. All the punches before 1781, which I could find, I have reproduced in my publication WIENER SILBER - PUNZIERUNG 1524-1780 (WIEN 2004). Unfortunately, your logo is not included.
