Brad never asks… he should at least send out an RFI to support his posts. He should know by now that Craig’s archives are full of AFV and cannon pictures.
But don’t forget the “forebears” of the M42.
The M16 Multiple Gun Motor Carriage (yes… that rolls right off the tongue) with quad .50s was among several self-propelled anti-aircraft weapons built on the trusty M3 half-track chassis during World War II. The M16 was perhaps the better of the lot, and saw service well beyond the World War II years.
Arriving just at the close of World War II, thelacked the “sexy” name, but was comparable to the in many regards. Armed with a wartime version of the twin 40mm Bofors, the M19 used the chassis of the M24 Chaffee light tank.
Lots of duckhunter stuff!
