How do I tell a back carburetor from a front one?

Let's suppose I'm at a swap meet and a vendor has an end carburetor for sale... How do I tell of it's a front or back? Is there an easy to identify a front one vs a back one?

The list numbers stamped on the carbs will tell the story. Here is a short list to use as a guide...
