I could guess, and be totally wrong, that the gun is pivoted around one trunnion axle
which itself is mounted in some kind of arm pivoted around another trunnion axle.
This would allow the gun trunnion to elevate and allow more elevation or depression
when needed.
If a picture is worth a 1000 words, digest this; there appears to be a forward and a rear trunnion axle
Nah, we totally promise not to tell about it to anyone.
Discretion guranteed …
