Luger pistol
On the morning of Sunday August 9, 1931, Kippenberger and Neumann gave a last briefing to the hit-team in a room at the Lassant beer hall. Erich Mielke and Erich Ziemer were selected as the shooters. During the meeting, Matern gave a Luger pistol to a fellow lookout and said, "Now we're getting serious... We're going to give "Schweinebacke" something to remember us by."
