  1. G'day Will, Perhaps I can answer a bit here. According to this page the Expéditions Polaires Françaises set up their first base in Antarctica in 1950: https://www.institut-polaire.fr/ipev-en/support-for-science/antarctica/dumont-durville/ These Ambilary-style french tracks did not have rubber grouser pads. The antarctic terrain can consist of extremely hard ice and was very punishing on Weasel tracks. Instead of pads they had ice grousers hacksawed (from personal observation) from pieces of stainless steel angle, with three teeth each. They were bolted to the outside edge of the grouser. On the last photo above, you can see two of them still on that track. I don't know whether they were fitted to all grousers (I don't think they were) or just every nth one, but every grouser had four holes drilled for fitting them. IIRC only two bolts held the toothed piece on. EDIT you can see the two bolts at bottom centre of the photo. Regards, Steve Brisbane, Oz
