Kilohertz,
The barrel is correct, as it should be 20 1/2" (actually, 520mm to the bolt face, or 20.47"), the stiock is correct for a 4100, so "theorically" not a 1600 by name (but same "familly") but a genuine American model. But it orignally came with a ramped and hoooded front sight. The year of production is late 1956.
Everything seems totally legit (marks, stamps and all) on both the stock and the barreled action. The number under the action is supposed to be either a specific pre-assembly serial and the letters on the stock are approval of inletting. The recoil pad is not original, but may have been installed at the moment of purchase.
While I have a different view than vviking about the rear action screw "tube", I totally agree with glass bedding your stock. My point of view about the tube is if it's flush with the wood (top and bottom) and should be alright as it's used to both snuggly clamp the trigger guard and bedding, as long as the front action lug is well bedded. The tang also must have the relief from the wood at the rear anyhow.
The removable magazines (the original ones, anyways) were available in the days and made in Sweden but are long dicontinued, but still show up in auctions there.
