A late war soft shell holster with a RB number and a police eagle.  These holsters came in with the Russian imports a few years ago.   They are somewhat controversial.  I have no doubts that the holster was made by the Germans during WWII.  Little is known about the RB numbers so they are subject to discussion.   The police eagle on this holster and most that I have seen has no letter in the chest area.  The letter typically seen on police holsters is a "B" and a few with that marking has been reported with the RB number.  Also, there is no swastika in the circle under the eagle.  The same thing has been observed on other equipment and is probably okay.
