Sweden originally had a contract with Remington for military rolling blocks. Most of those, like mine were converted into sporting rifles by Carl Gustav. I believe Carl Gustav and Husky (I'm not even going to attemt to spell it) also produced Rolling Blocks under licensing agrerments with Remington. Those will be marked by their own names respectively. As far as I know they are every bit as good.
As for mine, it's got the Remington markings on it, but on the barrel, it has the Gustav crest and some other markings. One of those its a 2 digit date stamp, which corelates to the year of "sporterization". Mine was done in 1896. When they did, they changed te barrel, and hardened the receiver, and block so it could handle smokeless cartridges. I've never done so with mine, it's probably strrong enough, but I don't want to chance it.
By the way, there's a nice .303 Martini Enfield at Simpson's too for $395. I wish I had the dough, I buy it.
Hope this helps.
