Infrequent portraits of members of the Berlin Freikor Freisch├╝tzenkorps ("Free Rifle Corps"). After the dissolution of the Corps, its personnel joined the Berlin police (neue Polizeitruppe von Berlin). Buttonholes of the Berlin Volunteer Rifle Corps (Berliner Freisch├╝tzenkorps) - the first metropolitan law enforcement structure.
A large number indicates a group (Gruppe), on the buttonholes shown this is the 2nd group. The small number indicates Abteilung - on the buttonholes this is the 4th abtailung.
Portraits of the ranks of the Berlin Volunteer Rifle Corps are quite rare, since this structure itself existed for a short time (1919-1920).

Does the description match?
