Extra Kollsman Altimeter Pointers

What do they indicate at 29.92? How fast do they move (if you take
them
to indicate an altitude?)

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.

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

Mitty,

When I set the Kollsman window to 29.92 today, the main pointers show
about -200 feet (which is correct as the barometer now is actually
30.15). And as I mentioned, at a Kollsman setting of 29.92, these
extra pointers show 1,740 feet regardless of the actual barometric
pressure.
