It would probably help in understanding. Jim, if this model wing of

Just worth noting here that a wing can be attached to the ankles and
still be primarily narrow in its chord through most of its length.
Therefore presuming a broad or narrow overall wing, based only on
attachment, is a error. The outboard wing in every well preserved
brachiopatagium is narrow. At the same time, several specimens seem
to show some hindlimb attachment - the most simple explanation is
therefore that the attachment was broad but the wing was narrow.
