The bolt collar give it away. It is not a 98 Mauser. All the 98's has a much larger collar containing the cocking piece (sear) and the safety lever on the end of the bolt.
Maybe an 93 or 95 check the bolt face. The 93 has a flt bottom the 95 is round.
The front sight wings are curved like the 1929 Oviedo Spanish Mauser.
