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.
On behalf of a friend I would like to enquire
1) When was the four figure postleitzahl introduced in Germany - 1961 or 1962?
2) What system was behind the 1949/61 postal codes?
3) Is there a booklet on the subject?
Thank you,
JM.
