For some reason, this was one of my favorite Little Green Army Man pieces when I was growing up. There were a couple of small howitzer variations by different manufacturer's back in the day and I just kinda liked their looks. Growing up I always had these hanging from the back of the Jeep as depicted in catalog illustrations, and that's how I photographed it here. The Howitzer measures 4 1/2" (11.43cm) L x 1 5/8" (4.12cm) W x 1 1/2" (3.81cm) H. Enjoy! Opa Fritz and Oma Bettina
The Jeep + Howitzer configuration is what I remember from catalog illustrations growing up and how I played with these as a kid. After perusing the Internet I did notice that Marx box art for the Battleground sets did show the howitzer being pulled by the Halftrack - a more likely real-life scenario. The Halftrack would also probably have been hauling the ammo needed for the gun. When looking at these photos it is clear that the Jeep probably would have struggled hauling a piece of ordnance like this gun and may have been a last resort if needed on the battlefield.
