 A 1946 merger with "TS Blau-Weiß 1923 Hamburg" helped advance the club to second division competition until league re-organization the next season again marked "St Georg" as a third-tier side in the Bezirksklasse Hamburg (III).In 1966 the club captured the division championship in what had by then become the Verbandsliga Hamburg-Hammonia and was promoted to the Landesliga Hamburg (III) where they immediately captured another title but were unsuccessful in a bid to move up to the Regionalliga.League re-organization in 1974 again saw the club dropped down one play class as the Landesliga Hamburg became a fourth division circuit.
