Any Savage 99 collectors here?

I'm looking for someone who can help me on a quest. I have been looking for a savage model 99 chambered in .300 savage but I am not entirely sure what the differences in the models are. The problem is that I want an ORIGINAL 99 but it seems like they all have something different about them whether it's the sling swivels or the stock design. I like the look of the models with the curved forend. If one has a scope how do I know that it has not been drilled and ruined so to speak? I could really use some help in this quest.
