[Grove]

Definitely folded, in which case, yes, 76r would be the first recto of the singulion. 

The same is true for 105r, which also begins with a large glyph.

To answer your other question:

You can't bind singulions together in a medieval sewing structure. It wouldn't work, structurally. The bifolia would have been an unbound pile that was nested and bound later, likely by someone who didn't know what else to do with the bifolia.

Would the singulion view make quire 9 foldout ‘cover’ or starting page be 67r2?
