Further to my last message,
On rechecking my albums I find in fact that there were two major parades in 1955 (not 1956 Lauren - by then we were down in Minden) - the first one was the Allied Farewell Parade for Major General Oliver in April on the Olympischer Platz then the Queens Birthday Parade in June inside the Olympic Stadium proper.
There are some 20 photographs ( total of about 791KB) of the first parade and 14 (total of about 790KB) for the QB one.
Will keep looking for others removed from the albums for various reasons and never put back, ending up in a yellow plastic box.
Cheers,
George.
