Did the fighters in WWII provide any indication to pilots regarding the amount of ammo they had expended / remaining?
For example, was there an actual counter for the number of rounds passed through a weapon, or some sort of electrical timer activated by the trigger button to record total firing time?
I'm thinking that those guys had nothing, and simply had to try to remember the cumulative time for which they had been firing.
I dunno, just guessing, too lazy to research.
