German Nebelwerfer 42 & Raketenwerfer 43 with Crew, made by Caesar Miniatures in scale 1/72 Part number H093. A fantastic kit that fits extremely well on a diorma. I bought this kit especially for the characters poses, just see the sitting soldier looking in the binoculars. If you do not already own this kit, buy it!
