You should have a number like this on the air horn of the carburetor body. It does not have a serial number but it does have a date code which has a relationship with the VIN and build date of your car.
The bowl is where the vent would be and that part of the carburetor has no numbers and could have been changed. The end carbs do not have vents but the center one does.
