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.
I have a p/card with a Marine Schiffspost p/mark with No 52 sent from Port au Prince in 1917. Can you please identify the name of the ship and is there a list of Marine Schiffspost numbers/Ships.
