Cadillac Carter 2 bbl carb

Anybody have any info on these 2 barrel carter carbs and what years they came on, and also the early 50s cadillac stromberg carburetor. I was told the 2bbl carter carbs were pretty easy to find but i'm having no luck.

 

did Cadillac use the Carter WGD?
Oldsmobile used that carb too,also Pontiac straight 8,and Buick.

 

Yes, I must have at least half a dozen of those things from the last yard we cleaned out, that were loose in cars. WGD, WDO, maybe another kind too.

 

Do you have some info for model carbs/size specs/model cadillac? Lookin to find four solid ones
