I'd guess the Bonnas at least are 70's vintage, some of the others may be as well. Downhill oriented skis got metal edges in the 30s/40s, touring oriented skis still haven't. XC skiing had a huge head of steam in the 70's. Thousands of XC skiiers in Yosemite - they banned snowmobiles partly for public safety. It wasn't until late in the decade that fiberglass took over, there are quite a few wooden skis still floating around, including my parents garage. Fun to ski. "Tur Model" is a touring ski, "hickory sal" is a hickory sole. You probably saw this website before:
www.woodenskis.com ; I can try and dig up what I have buried. I might be interested; I also have a pair of Abercrombie & Fitch skis to resuce. How times have changed.
