Have any ex-airborne out there seen this kind of chincup attachment before? The helmet has Canadian service numbers all over the shell and cover, so I'm assuming the liner was used by Canadians as well. It is a standard US made para liner, dated 1982. Obvious signs of the pronged buckle being removed and these slider buckles sewn on to accept the different chincup. I've seen a lot of para helmets in my day, but none with this modification.
