That's a 1951 FN commercial action that originally came with a Sako over-ride trigger with a plungers sear instead of lever.
That one has a German made Flaigs barrel and replacement bottom metal and looks to be either a Bishop or Fajen semi-inlet stock. (Cheekpiece could say for sure).
Originally, the bolt sleeve had a quarter turn safety on the LEFT side. If you look into the action near the chamber on the left side, you can tell about when it was made. If the inner ring is solid, it was before March of '51. After then the inner ring is broached all the way through.
The serial number on the receiver means Flaig's installed the barrel instead of selling the parts.
The stock has an oddity-- Utility grade wood is very common but a Neidner butt plate fitted to it is not even though the butt plate 'fits' the barrel theme, the rest of the stock does not. It is a 'cross-culture' rifle.
The styling is usually pure European as shown below (with replaced butt pad). Very trim, slim and 'tiny'.
You have a very nice rifle!
Check the muzzle. Those barrels are a natural $*&@#^ to crown and some aren't done very well.
