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 recall reading in a red backed book on feldposts many years ago that there was a flight out of surrounded Posen taking mail out of the fortress on night of 8/9 February 1945 - any information please!
