I don't think Tinder Qwik was available back then. We had things that were available back then and previously. Seems any product with wax or better yet, Bee's wax impegnated is pretty reliable for lighting and burning for a reasonable time. I carry a Spark-Lite with the Tinder Qwik in my packs as one of my firemaking options and consider them reliable. Check that the flint hasn't oxidized into dust in the Spark-Lite though. I have the aluminum model that I can remove and check/replace the flint. Well worth the extra few dollars!
