very nice one ! My compliments.
The double headed eagle made me think of 3 potential "culprits" :
Russia,
Albania,
the Holy Roman empire

but most likely it is or could be related to Ali Pasha of Ioannina

who had his role in the strive for independence in the region, next to being a link to the Hellenistic region .
Tip for those interested in the latter; a most interesting and beautiful book... "Captain Michalis / Ο Καπετάν Μιχάλης " (AKA Freedom or Death) by Nikos Kazantzakis
