Austro Hungarian Silver Decanter Identification

Can anyone help me identify the maker of this decanter based on the hallmark (initials A.P.)?

Based on my own research, I’ve discovered that the piece was made between 1872-1922 in Prague, back then part of the Austro Hungarian Empire.
The second hallmark, representing a double-headed eagle, is pointing to the Coat of arms of Austria-Hungary.
Taking into account these arguments, I don’t have any doubts regarding the place of origin. The only information left unknown is the master behind this piece. Any help would be appreciated.
