I had years of AH-1Zs pics, but none with fuel tanks loaded, so of course the next two air shows I went to had AH-1Zs on static with fuel tanks.
The ammo bay doors on the Czech Republic and Bahraini AH-1Zs did not have the riveting that I had seen on Marine Zulus. A door with the rivets is shown below.
Doors without the rivets can now be seen on some Marine Zulus.
