I was a bit perplexed about this question............. IN the Britishicon Army, we never had Sterling mag pouches as such because we just carried our magazines in our bog standard ammo pouches - as our tame Triumph man GSimmons says quite rightly. To use these, you'll need two of them plus the belt and yoke too. Readily available on ebay. Look under '58 pattern webbing' or even '44 pattern webbing'
