Yes, the proof will be in the pudding! Thats is, will it hit what you are shooting at! . Not a thing wrong with that rifle from the photo.
As for a sling....... a period correct one....... well I have a sling on a used Miroku I picked up. Previous owner installed. I suppose it's ok. One of them Uncle Mikes clamp on the barrel thingy. Not all that correct. I suppose if you wanted the really period correct ones you should have a swivel "eyehook"" sweated on the barrel forward of forearm. That uses swivel hooks like a Model 54 Winchester. I have a set on an old Mauser sporter. This could promise to be a real PITA to set up! And mebbe a bit pricey.
My suggestion would be to not install a sling!!!!!
