The Brobenzyl-Wurfkörper 32 (BBWK 32) was a teargas grenade.
The all cardboard construction contained a friction fuze, a delay
element and 2.2g black powder to fracture a glass vial, containing the teargas.
As the grenade was sensitive to moisture it was short-lived and replaced by the BWK 34.

The photo on the right shows the transport case for 3 BBWK 32 gernades.
