The model did not come equipped with the chin mounted 20mm Gatling gun. It did have a search light attached to the belly of the aircraft which does not appear in the anime at all. I cut the search light off and drilled holes in one end into which were glued lengths of black wire to make the three barrels of the gun. A very small piece of plastic was cemented in between the wires near the end to make the spacer that modern Gatling guns have for stability.
