Here are two vintage, pre-WW1, photos of the use of a straight-pull M95 Mannlicher sporter. From the book "Karpathenhirsche" = Carpathian Stags by August von Spiess, Austro-Hungarian, later Romanian officer. The author is shown with two of his magnificent stags and his sporter. According to his writings, he used such an 8mm Mannlicher sporter as early as 1896.
