Coat of arms of Franz Michael (František Michal) Daller, abbot of Strahov Monatery, Prague (1764 - 1777). Version with wrong tinctures of the coat of arms of the monastery, but used by the abbot Daller himself (1st and 4th gules instead correct sable). Based on description in Bibliotheca Strahoviensis, 1995, p. 18, 19 and on the gravestone of abbot Pfeiffer in Malá Strana Cemetery, Prague.
