 An off-centred disk version of the swastika flag was used as the civil ensign on German-registered civilian ships and was used as the jack on (the name of the German Navy, 1933–1945) warships.The flags for use on sea had a through and through image, so the "left-facing" and "right-facing" version were each present on one side while the national flag was right-facing on both sides.From 1933 to at least 1938, the Nazis sometimes "sanctified" swastika flags by touching them with the (blood flag), the swastika flag used by Nazi paramilitaries during the failed Beer Hall Putsch in 1923.
