Somebody has the coordinates, references
or image file of Irv Culver airfoil?

Irv culver did a handful of profiles for Jim Maupin
gliders; but I have no idea how the profiles are related.

This page suggest that there were two or three profiles:

It calls them the Culver, Culver 18%, and Culver SD.

This page has coordinates for the root profile of the
Maupin Carbon Dragon, which purportedly uses the Culver
SD:

Note that the root and tip profiles are visibly different.
