Need delta wing reference for figure shown in Hoerner book

[53K]

Hello,
I am trying to find the source for delta wing wind tunnel data that is shown in Figure 24 of the 1975 version of "Fluid Dynamic Lift" by Hoerner. The attached file shows the page from the book (or can be seen here:

http://www.foremostengineering.com/retrieve/hoerner.pdf).

The data is for delta wings flying with the point facing backwards. It may have come from Lippisch.

I would like to know if there is drag and pitching moment data in addition to the lift data shown. And if the models had airfoils shapes or were flat plates.

Thanks

Sounds like a tough case to solve. Why not gather up the other references that you can from the chapter and see if they point you in the right direction? With Hoerner, I wonder how much of the unreferenced data comes from his work in Germany during WWII.
