This passenger car is most probably an Adler Standart 6, which was manufactured from 1927 to 1934. Possibly it is a variant which was made for the Reichswehr. Beginning in 1927/28, the first Reichswehr Kübelwagen were built on its chassis.
The Adler Standard 6 touring car was procured by different police departments and also by the Reichswehr.
Also this Adler Standard 6 touring car with the license number RW-2800 was used by a unit of the Reichswehr.
The Reichswehr procured some limousines of the type Adler Standard 6, too. This is proven by the illustrated photo of the vehicle with the license number RW-1345.
