Are they showing pressure altitude? Are the main pointers showing 1,740 at
29.92, too?

If I set the Kollsman to 29.92, the little pointers indicate 1,740 ft.

They only move when I turn the Kollsman knob and the pointers turn in
sync at the same rate as the hundreds and thousands regular pointer
hands move. The pointers do NOT move with actual air pressure changes,
only when I manually rotate the Kollsman knob.
