That's not a 'regular' Model 1924 Yugoslav Mauser, but a Model 1924b. The latter are significantly harder to locate, especially in anything but worn, beat condition. This is summarizing things quite a bit, but they were made from German Gewehr 98 parts, and then brought up to Model 1924 specs. That's why so many of your small parts bear Imperial German stamps, numbers and frakturs.

These aren't usually found with matching bolts, so yours is definitely a plus. Where's the rest of the rifle?

A pic of the stock would confirm if it's correct or not. The other pieces needed can of course be sourced from G.98 parts, as you noted.

That's definitely not the stock that the Yugoslavs put it into. It should have a cut-down Gewehr 98 stock, and should have the bolt take down ferrules and Imperial proofs, among other aspects.

How would it be 'correct as a Yugo rework' if dropped into a FN stock? The Model 1924b series never used anything but Gewehr 98/Mexican Model 1912 and domestically produced Yugoslav components.

Here's a pic of my 1924b trigger guard and floor plate if it helps:
