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.
Does anyone know how many post offices were in Stettin during the Third Reich era? I bought an enormous amount of Hindenburg parcel card clippings very cheaply and there are a lot from Stettin. So far Stettin 12 is the highest one I've found.
