I would call Bourbon if I were you and explain what your lookin for, she is also in Tennessee and may know of or have an older glider.
Bourbon is the B in Bml
and creator of the Custom Cruiser wheels
321-331-1608 is her number, she is near Clarksville, you can tell her Carla sent you
There is also a Clarksville group on facebook, great place to meet glider folks local to you or at least in your state.
