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.
Could please advise me of the meaning of the capitalised initials B.O.G. or they may be B.O.C.
They appear in black as a handstamp on an entire letter dated 1845 from Passau to Wien (Vienna).
Thank you in anticipation of your help.
Colin
