Chris, I tried to get as sharp an image as possible, but there isn't
much to see. From some on-line searching, I gather that sailplane
pilots like to have variometers that show both the vertical speed of a
rising thermal column and the vertical speed of the aircraft. Maybe
that information is provided by these instruments, but the details
have to be in the head of the pilot.
Neither of these is a g-meter. I think the markings give vertical
speed in knots.
