Roden 712 Sd.Kfz. 4/1 Panzerwerfer 42 (early) 1:72

The prototype was built in early 1943, designed simultaneously as a vehicle fitted with a ten-barrel rocket launcher, and a transporter of ammunition for it (because a full set of rockets took up considerable volume, only 10 additional rounds were carried by the firing vehicle). The transporter could carry up to thirty rounds for the launcher. The Opel Maultier's chassis was surmounted by an armored body of varying thickness on all sides, and the launcher was mounted to the rear of the body, capable of firing in a horizontal arc of 270 degrees.

One difference from the Soviet BM-13 was that there was no need for the crew to withdraw from the vehicle during rocket firing - they simply sheltered inside the body. If necessary, the crew of four men could quickly leave the car through the back door, and when the car was in motion, the driver viewed the surrounding area through narrow openings in the front armored shield.

The gunner who was sitting on a movable seat operated the firing,directly beneath the launcher. The commander of the car was also its radio operator, while two other men drove the vehicle, and loaded the launcher. In combat the armored car, given its official name of Sd.Kfz. 4/1 Panzerwerfer 42, could provide some defense against enemy infantry using its MG-34 7.92mm caliber machine gun.
