Still have a compass?
Yes, the COOK compass was/is very useful for coming out of cloud
on the right heading; I still have one on the shelf.
It could be compensated with tiny bar magnets inserted in one
of two orthogonal holes in the bottom. Why bother so long
as it shows the right quadrant?

In the UK we used to have a non-compensated compass, by Cook, that could

Bohli can do it like the Cook compass =96 but I don=92t know if Bohli can

It is an impractical and almost useless legal requirement, imho.
I don=92t know of any ramp check while in cloud, fortunately.
