The British gunmakers imported the Mannlicher M 92-93-95 turnbolt rifles in miltary shape and then sporterized them to different degrees. Higher grade rifles were not only resighted, but restocked too. The “economy” lower grades retained the shortened, reshaped and maybe checkered straight grip military stocks they came with from the factory. On this M93 Fraser too retained the straight grip issue stock, but reshaped it to the distintive "Scottish" style and added the seperate pistol grip.
