Developed in the 1930s, the Nebelwefer 41 ("Smoke Thrower") was a towed rocket launcher in German service between 1940 and 1945. Capable of firing a six rocket salvo over a period of 10 seconds the Nebelwefer's 150mm projectiles produced a very distinctive howling sound. This lead to the Allies nicknaming the weapon the "Moaning Minnie" or "Screaming Mimi". This is an issue of the MK72 mould that was never released by MK72.
