I’ve got an original a12 Bee with the original manifold. It does NOT have the funny 6. I’ve got two more that I bought many years ago with original dated carbs. They look the same. My car was built about the middle of production. I do have one intake with the funny 6. It to supposedly an earlier cast intake. All the carb holes look the same and are not real clean cut like later over the counter intakes either. I bet yours is real.
