So our museum, which is part of the Commemorative Air Force, recently acquired a 1943 halftrack with a quad .50 AA turret in the back. I'm not sure how many halftracks are in working condition now outside of reenactment groups, but ours is all original and was just repainted back to how she would've looked at the end of the war. The turret, which is operational, and the armor are all the original ones put on it at the factory and we have records showing it shot down six German recon planes as part of the Third Army. The best part is though, the guns work. Sorta anyways. They burn a propane/oxygen mixture that they "shoot". I managed to get a short video of the turret being tested before a show at our airfield.

As well as the markings for the planes shot down

My question is, does anyone know how many of the other surviving halftracks are as operational as ours?

Where is this? I would like to see a real one! I've only been able to see replicas, or just plain models.
