The oldest pair of skis were found in Hoting, Sweden and are estaimated to be about 5,000 years old by carbon dating.
Wood.
Yes, you can just make sure they have the same width and specifications as your old ones.
It depends on what model of skis they are and how long they were used. If you go to a ski shop they can tell you and they might even buy it from you.
Skis weren't just found - they were invented. No single person is credited with the invention of the original ski. According to the International Skiing History Association, the first record of skis is from rock paintings and skis preserved in bogs that are at least 5,000 years old. These ancient skis were used by hunters and trappers.
No need to wax...best thing to do is preserve with linseed oil.
My sister had some Rossignol Challenger skis (150cm) back in 1977-78. Not sure if they updated them since then.
The bindings come with installation instructions, but if you got used bindings that didn't come with instructions... Quick question: are you putting these on new skis, or on skis that already have bindings on them? If they're old skis, remove the bindings already installed and use the old screw holes for the new bindings. If they're new skis, take them to a ski tech. You've got to drill holes in your skis and there are lots of calculations involved - how much you weigh, the skis being used and the way you ski determine where your boots should be on the ski.
Everyone is born with skis on their feet.
I recommend you don't try that. It's a difficult process, and it's an industrial product. But of course you can do the old wooden skis way, but then again. That won't go fast ;)
"Les skis."
You can't get skis.
