This one is a little odd though; it has a triple carb setup. (didn't look too closely to see much about that yet - who made the manifold and carbs - as it runs solid). According to Dad it came that way from the military when he bought it.
Not to dispute what your Dad said, but I doubt if it came directly from the Military to him with triple carburetors. From my experience with military stuff, they were dirt simple and as cheap as possible. I really doubt that the military would have coughed up the funds for a 3-carb setup.
