OK here it is in the final version. All Ground and Aircraft mounted guns have been tested. This post can be used as a reference for damage in Aces High version 1.11 patch 4. When AH II comes out we can see what changes were made if any.
I'll work out a nicer, prettier version of this information and post it to a website when I find the time and energy.

* The Vickers S and 37mm HE Ostwind are the only weapons I
am not 100% certain of the full series of tests had very
inequal results. The value shown is the maximum damage
inflicted per round. I suspect that the variance is caused
by a bug in the burst dispersion code.
#1 Testing for the GV main guns was different. I fired 1
round into a hanger and constantly tweaked the hanger's
damage resistence until I found the maximum single round
damage.
