Oerlikon 20mm Ammunition Locker x 4 1/48 Scale. As found on a variety a Coastal Forces craft during WW2. Suitable for printing in the Frosted Ultra and Extreem detail plastic. Some very light sanding may be required to remove z axis lines created by the printing process. Primer, and acrylic paint can be applied for a smooth finish. Details and recommendations can be found in the forum. If short sections of the sprue are left attached, these can act as locating lugs for a more secure fitting. The Frosted detail plastic can be quite brittle, so care must be taken to avoid damage to the clips, while handling. Please PM me if other materials are required..
