You can take an altitude angle measurement by turning the compass on its side and adjusting the spirit level
(while viewing the spirit level using the mirror hinged at 45-degrees).
This model F5006LM is accurate to 1/2 degree in azimuth, and has a 10 arcminute resolution for vertical angles.

The F5006LM has a National Stock Number of NSN 6675-01-127-8394.
The list price for the F5006LM Brunton Compass with leather case is $538, but we are offering
it for only $449.
We receive many complaints and there is much confusion about Brunton's
claim of an International Balanced compass needle.
It is widely assumed that International Balancing means that the compass
will work at any geographic latitude.
According to Brunton, International Balancing means that the compass will
perform properly at any longitude within a specific range.
This is misleading because compass balance is affected by the Earth's magnetic dip
angle which mainly varies with latitude, not longitude.
Brunton offers three models each balanced for a specific region: Northern, Central,
and Southern latitudes.
We only stock the model balanced for the Nothern latitudes and Brunton
does not offer free rebalancing, but rather charges $40
to rebalance the compass.
