Bohli Compass

You can fly IMC (ie climb in thermals in cloud and straighten up on a
heading) on just a Bohli, ASI and slip ball, I have done so in the past to
prove the point. It is very high workload and taxed me near to the limit
and I have far more cloud flying experience in gliders than most pilots.

Then you could do it also by looking at gps track instead of compass. I have only enough IMC experience to not try that kind of stunt.

Actually, that's not the case, a Bohli gives (by inference) angle of bank
information as well as heading. If the indicator is tracking
concentrically with the instrument then the instrument is tilted to the
aircraft's angle of bank. If it isn't the you change the angle of tilt on
the compass until it is.
