Interesting later 99 in 300, what model is it?

I have a later model 99, Serial number 6457XX.
Savage guns are new to me. I'm considering selling this rifle, but I have not been able to find out what it is, or it's worth.
Can you guys help me out?
Here's what I've figured out so far;
It:
Is chromed
Has the pop-up pin to show when the gun is cocked on top of the reciever.
Has a lever safety
Has a rotary magazine
Has an oval round counter
Is chambered for .300 Savage
Has triangle-type checkering on the
forestock

When you say "is chromed" is it the outside of the gun that's chromed instead of blued?? Can you post pictures??
