Carb and Divorced Choke issue

This car you've pictured has not got a Super Six (which came with a Carter BBD only; the article stating a 2280 was factory equipment is in error. Holley sold 2280s as aftermarket replacements for the BBD, and the 2280 was factory installed on some V8s.). Your car has a Holley 1945 1bbl carburetor. The list number (and the factory service number) are stamped on the side surface visible in your second-to-last photo. It looks as if someone's gotten a little carried away with a can of Chrysler Blue spray engine paint.
