Plenty of references, if you look up the artillery in XIV Army in Burma. 3.7 AA was regularly used as arty there - if the terrain was flat enough for the battery to engage (ultra flat trajectory meant no real ability to engage any targets in any sort of defilade). Esp later on in the war, when there was no real air defence task.

However - not really worth putting in the game, a troop of 25 pounders does the trick as 3.7 in ground pounding mode.
