This close enough to what you're after?

The ordinates given are for an aerofoil derived from Bo-560-26.

I think that some (maybe 5) Bill Bogart airfoils are mentioned in the Davis Airfoil info in the plans section.

Some information was received from Sergio Montes, Free Flight Quarterly, January 2006. Free Flight Quarterly is always highly recommended. NFFS Sympo 1993 has Ph. Kruger paper on the Davis Airfoil on pages 97-110.

Henry Cole's article on Davis airfoils appeared in Air Trails, May 1942. Sergio gave Hank Cole's five favorite airfoils as A=1, B=0; A=0.6, B=0.1; A=0.90, B=0.10; A=0.93, B=0.17; and A=1.00, B=0.20.

These are easy to plot and print from the Davis Airfoil software in the HPA Plans Section. Deciding what to use and why is not easy, so good luck.

I did not answer your question, I'm afraid.
