I need help, please, identifying which version of model 99 we have here. It is serial number 529513, in 300 Savage caliber. There is an "SP" in an oval on the left side of the barrel near the receiver frame. It has a brass rotary magazine, but I do not see a counter. It has a tang safety and a slightly curved steel butt plate.
Thank you in advance for and insight you can provide.
