 Altimeter identity
I don't know if this is the right place for this query but because of
the requirement to register it with the CAA I need to know the maker of
the altimeter in our sailplane.
The instrument appears to be a bog standard 3 pointer altimeter with the
millibar sub-scale in a window at the 6 o'clock position as is the
pressure setting knob.
There is no indication on the back of the instrument other than a broad
arrow.
On the face of the instrument there is a legend KB4/O2KA Mk20A, and
separately the figures 11/56 (date?).
Under this there is what I think is an Air Ministry stores reference
Ref 6A/3155.
Anyone any ideas?
