This may only be of interest to a limited number of more specialized Victory fans, but by posting it here I hope all who can use it will see it.
While researching another type of gun in the historical collection of the Berlin police, I came across this comprehensive list of stampings put on all Victorys issued in the American sector of Berlin. The Victory is listed as on active duty from 1946 to 1964. In 1963, West Berlin police began standardizing on the Manurhin-Walther P1; the special four-power status prohibited German-made guns.
Markings are on the backstrap. I remember encountering at least a few here over the years. They consist of a star and the letters:
BAK = Sector Kreuzberg
BAN = Sector Neukölln
BAS = Sector Steglitz
BASC = Sector Schöneberg
BAT = Sector Tempelhof
BAZ = Sector Zehlendorf
