Rob,
As I understand it, the practice varied between nations. Brit guns in a two-gun Section had one gun with two round-head posts, the other gun with two square head posts.
Aust guns carried one of each, which meant when working in a two gun Section, a quick swap between guns was done to provide two posts with the same head type to each gun. This meant that guns could be moved between Sections or Troops without having the possibility of two guns in the same Section both having the same aiming post head shape.
Don't know what other Commonwealth nations did.
