The year 2014 marked the 50th anniversary of the first year of operation of the Germany & Colonies Philatelic Society following the amalgamation of the Germany & Colonies Stamp Club (established 1947) and the Stockton German Study Group (1960).
The G&CPS celebrated its inaugural year in 1964 with the first Germania Posta philatelic exhibition held in Stockton.
Was there private postal agencies in Constantinople who operated for the German postal authorities. I have two cachets on Russian postal stationery postcards referring to Deutsche Post (Antoine Angelides) and Post Allemande 144(Filiberti Stoppani)
