Cut-down anti-aircraft shields improved handling and visibility

Why were the anti-aircraft gun shields in images of Maggi cut down in size?

Less weight makes manual or hydraulic training easier, a lower shield improves visual identification and aiming, and every reduction helps control topweight.

Protective plating is not free once it has to move with a weapon high in the ship. Reducing the shield lowers the mass that crews or hydraulic gear must train against an aircraft. It also opens the gun crew's field of view when targets are identified and engaged visually. The remaining saving is valuable topweight, so the modification trades some protection for faster handling, better awareness, and a more manageable ship.
