Set the current altimeter setting on the Kollsman window. Remove the altimer
from the panel and hold the altimeter with the face of it pointing to your
"left wingtip". Look on the outer edge of the case right near the altimeter
adjustment knob. There is a very tiny hole in the case covered with soft
black goo. With a very small eyeglass screwdriver, remove the black goo to
expose the head of a very small flathead setscrew which extends radially
toward the center of the instrument. Remove the setscrew completely. This
will allow the altimeter adjustment knob to be pulled out about 2 to 3 mm
further than normal. This disconnects the usual interconnect between the
Kollsman window and the altimeter pointers. Now rotate the (normal)
altimeter adjustment knob to set the correct altitude for your current
location. Push the knob back in to it's original depth. Reinstall the
setscrew, and you are done.

My Winter 57 mm 20,000 ft altimeter reads about 200 ft high when entering
the barometric pressure in the Kholsman window. Some altimeters have a
screw adjust for this. Anyone know how this is done on the Winter?
