As you are aware, the public Carter Y-DNA project is fairly transparent and shares some of it's data online, without infringing on each individual's privacy. Please see the links below. While I cannot say who tested, I can certainly answer any question about the Kit numbers and their placement in the project. In those cases where the family has provided pedigrees they are posted at World Families.
This is a link to pedigrees submitted by members to me [Robert Mike Terry email: firstname.lastname@example.org]
This link shows Carter DNA Project - Background (Includes general statistics).
This link shows the Y-DNA results with the FTDNA Kit numbers.. You can type in 1000 instead of 500 to see everyone on html page; otherwise, there are two separate pages. https://www.familytreedna.com/public/carter/default.aspx?section=ycolorized
This is the classic view of the Y-DNA results without colorization....
This link shows the SNP values for Kit numbers. Those green in color are confirmed by SNP testing and those in red are estimated from Y-DNA markers.
