The red needles on the diving gauges... It's correct to assume that they were used for steering correct depth, since they are on the gauges for shallow depth and that they are on both the gauges for both planes-men.
I think that the needles (they are 'adjustable') were set however the commander of the boat, or the diving officer wanted them. So, one for the attack periscope, and one for the observation scope. With the introduction of radar, that may have been used also. On the Guppies they may have been set to the snorkel depth, etc.
That you see different readings on various boats has a simple reason; people have adjusted them for whatever reason. The painted ones could have been made because the needles were missing, or the gauges had not been equipped with the needles. If you look at "The Fleet Type Submarine" you will find a drawing of the dive control station with gauges that do not have red needles. This could mean that this was a modification that was introduced during the war, or just after.
What they are currently set to is up to the discretion of the shipkeeper...
