well... I've not seen an altimeter in US aircraft that can dial out 5000ft
of altitude.. that would mean the altimeter would have to be adjustable from
29.92 to 24.92, and mine only goes to 28.10

It may be a regional problem. In certain European contries, QFE setting
is common for approach. So the altimeters sold here are designed for this.

BTW, when doing acro, the scale range isn't a problem. Just turn the
knob before takeoff until the meter shows zero. No need to have a
calibrated kolman scale for this.
