Props 3D Aliens Ithica 37
The Ithica 37 is the only successful commercial shotgun where the loading port is also the ejection port giving the gun and interesting look. The Ithica model used in Aliens had the rear grip and stick of a German MP40, giving it the district ‘hole’ in the back. We have replicated every detail of the original prop used by Hicks in Aliens using screen used references as well as reference Ithica shotgun. This model is a very easy glue together build, only requiring 5 optional screws to complete the look. It features a working pump for an authentic feel.
