Howdy Mepr and All:
The carb shown is a Holley #1940, factory replacement carb. The fact that it has the Autolite Logo cast into the body not withstanding. Note that there is a SCV for compatibility with the Load-a-Matic distributor. When Autolite quit manufacture of the 1100 and the 1101, Holley was licensed to make and distribute a carb as an official FoMoCo replacement carb. If it had a tag, it would likely have a "Z" in the code indicating "Service Part", meaning it is a replacement part sold by FoMoCo for Ford application.
In the case of a 223 in a '64 pickup, the correct carb would have been an Autolite 1101, C4AF with different suffixes trans type.
Not much is known about the Holley service replacement carbs as they are not original and are not a trouble free change. They are quite generic regardless of application. Sort of a one-size-fits-all fix.
That's my two cents, for what it's worth.
Happy New Year.
