Can anyone identify the probable original application of this Carter AFB carburetor? As you can see from the photos, it is stamped 3721S low on the casting but there is no apparent stamped date code. It has a six mounting hole body with casting number 0-1552 as best I can read. The upper tubes appear to be brass.
This carburetor sits on a block stamped F0103RD which appears to be right for the E9 build date code on the trim plate of this 1964 Corvette. I noticed the kink in the choke plate linkage which appears to be a non-standard for Corvettes. The accelerator pump linkage does not have a kink - is it possible to mistakenly swap these linkages on reassembly? As the photos show, the top of this carb was removed at some point as there are many screws missing there and the tag is gone.
I saw a question posed but not answered in the archives about the straight (or not) linkage so maybe that is a clue to the original application. My understanding is that the likely original Carter AFB on an RD motor assembled in January 1964 would be 3721SA and it would be date stamped.
So what was the likely original application of a 3721S carburetor stamped in this manner without a date code? Could this 3721S be set up to perform the same as an 3721SA or SB (is the difference just a question of jetting and swapable internals?) Thanks for your help, Joe
