You're seeing the back end of Salomon 222 and 'S' bindings.
They were WIDE for the day, the originals were 93-73-82, while the later versions shrunk to 88-73-78.
I did ski the original ones (180cm) the first day of my season this year (Nov. 25th). Nice ski in soft conditions. These have Look Nevada toes with Marker Rotamat heels....and safetly straps of course!
Nice collection, Bill. The Yahoo would have launched around 1975 and it went through several iterations but basically it was a short, soft, fairly wide wet-wrap foam core slalom ski -- a slalom ski for bumps and especially for softer western bumps. It was Head's freestyle ski.
Do I see Geze Olymp bindings from '76? I think this was the first binding designed to the new DIN standard so if the springs are good these are still safe to ski . . . So we expect to see you popping daffies on the Yahoos this spring. Or maybe they're Markers.
