[Bmcu] How to identify SU Carbs

[Charles Easton]

So I'm trying to sell these MGB SU carbs (as you all know), and due to the fact that I'm kinda new to this, and dealing with my less-than-ideal IQ, I might have mistakenly called these HS6 1-3/4" (which as I understand it, are more suited for the MGC).

After further investigation (cleaning the oil off helps), I found these numbers:

AUD505R and AUD505F on small, removable tabs that are attached to both of the lid float chamber screws.

AUD 9 is located on the side of the left carburetor base.

If you lift up the piston chamber assembly, you'll see these numbers on the inside surface of the carb body: JZX1214 on the left and JZX1215 on the right.

On the inside of both piston chambers (under the dashpots) you will see PDC16 and AUC 1332.

I think it's great that these were numbered so extensively, but finding the Rosetta Stone that unlocks the mysteries of their meanings is another matter entirely.

Can any of you experts out there lend a hand? I would be much obliged!
