In the 2005 Series 5 Small Army collection we bought #1 and the machine gun on the picture shows a 6 barrell machine gun. The actual machine gun in the package we bought only has 4 barrels and looks like another part is attached to it. Does it come in 2 parts and was our package missing one part? Or is it actually different than the picture and supposed to be only 4 barrels? Thank you.
