GI Joe 155mm Howitzer Part 2 in Travel Mode

Thought this one needed a second set of photos to show a few additional features. This time it is folded up for travel and being towed by an M-8 Greyhound. As you can see it folds up in the front and the back Also I took the projectile out of the gun so it could be in the photo shoot. I think there is a powder shell but I can't find it.
In the third and fourth photos it shows the recoil feature. The silver portion is exposed when the gun is fired or actually just when I pull it back for effect. It is powered by imagination.
