Yes, in fact that crest does appear to be the model 24...

Value in like new condition is 300-400$

(I was running out the door when I posted the info earlier so here is the rest. Hopefully it will help make to make your confirmation.)

----------------------------------------------


This rifle was the first to be accorded a Yugo-specific model designation. As Yugoslavia did not have their own rifle production facilities until later on, the 1924 pattern Mauser rifle was manufactured under contract by FN (Fabrique National D'armes De Guerre, Herstal, Belgique) and BRNO.

All were straight bolt rifles with the 'old style' long-type wood-handled Mauser bayonet, and all were produced prior to WWII.
