I'm going totally out of box, not even bothering with ignition wires.
I'm going for that war weary patch work of an aircraft. I'm listening to A Dawn Like Thunder, the story about Torpedo Squadron 8. When they were on Guadalcanal they ended up cannibalizing TBFs to get one or 2 flying. I don't know if any photos of those aircraft are around but I'm going for that same look with this early F4F-1.
