many ,many years ago,the magazine,fine scale modeler,had a feature article,on converting a M3 stuart,into the quad .50 prototype.It involed taking two Tamiya models,their M3 stuart and the pedstal mounted quad .50 from their M16 halftrack (the article mentions that this was how it was orignally done)ive got the issue,set aside,its my plans to build this in the near future,ive got the M3,the pedstal mount,the individual track links,just need to pickup verlindens .50 machine guns(i dont what to use Tamiya's .50's.)after testing,the military chose to go with the quad .50's,mounted on the halftrack.
