Missing from the photos are the original turntable Rotamats. These had a metal plate covering the heel unit with D rings attached for arlberg straps (post longthongs). When the binding released, not only did the spring bust loose from the housing but the plate pulled loose from the binding as well. The plate was attached by a short leather strap to the wire of the Rotamat so you didn't lose the ski. It was a lengthy process to reassemble the binding after a fall/release.
Also missing is the original Marker turntable heel. This one used the longthong as part of the closure mechanism. You'd wrap the longthong with the rear closure lever open and once everything was snugged up, you'd close the lever to give the maximum forward pressure. The heel was (obviously) non-releasable, but if you came out at the toe, a full longthong re-lace job was required before continuing on. I had that set up on a pair of VR7's.
