Yeh, I know what you mean on the barrel condition. When I bought my recently purchased 91/30 I thought the barrel was new, no, it is in excellent condition, but not new. Also, the bottom serial number on the magazine cover was lined out, and a new one matching the bolt put in. My last Model 44 was rebuilt with a new barrel, and all parts were matching. It shot well, but some of the guys at the range complained about the muzzle blast, it really did have a huge orange flame come out the front muzzle, recoil was ok, though.
I thought their reaction was odd, considering the number of super magnum rifles that are shot there where you can feel the muzzle blast shock on your face and chest stations away, 7 MM mag. 375 H&H, 338 mag. etc.
Anyways, I might regret not getting a second MN, and will do the research and try for fit and feel at a future gun show, but a carbine for sure...most likely a Model 44 as it is different looking in appearance, and I know they shoot well, will look at the Finn guns again too. This will also entice me to start hand loading for it, as the surplus stuff may get more and more difficult to find, also, the sticking chamber problems with the lacquered steel cased ammo is annoying.
