Finally added a pair of Siderals to my collection Now I'm trying to figure out exactly what they are. They are the version with 'Numero Uno', navy blue bottoms, and they are SLs. There are no serial numbers and no size marked anywhere I can find Is that typical? They measure out at 210cm ... quite long for a slalom ski! There is a worn stamp on the bottom but I can't make it out - see pics.
Gustavo Thöni skied and won on them at the Sapporo Olympics in '72.
