How do you determine whether a 99 is a Version 1 99R or 99RS? I'm fairly sure this is an RS that I'm looking into (1937), I understand the easiest way in my thinking/research is the forend with 2 lines cut perpendicular to the stock length (which this one has), (I assume that an RS should have a sight on the tang equipped from the factory, is that the only difference, same rifle otherwise?) But did Savage install T-7 mounts from the factory on either the 99R or 99RS version 1's? (the one I'm looking into has the T-7 style mount). And if Savage did equip either the 99R or 99RS with T-7 mounts on either, how would you tell if it were an R or RS, if the only difference is the factory installed/equipped rear tang sight? Does this look like an original sling mount on a 99R/RS?
