I don't have any closeup pictures, but can describe it:
The lacing was fabric and had three ribs, unlike the widely available reproductions which have two ribs.
Unlike the lacing on the cowl, there was no wire running down the middle.
The sections were held in place with two hex/clutch head screws with no washers or other devices to clamp the lacing down.
The lacing was long enough to poke through the two slots at the top and the bottom and maybe 1/4" to 3/8" went through to the other side.
