SN 258xxx denotes 1924 manufacture.
Since the .303 Savage is a .30-30-class cartridge, I'd want to be certain of ammo availability/cost, and pay no more than $350 for one with an aftermarket/modified stock.
Savage 99's have only been made with half-stock type forends of various configs, depending on model & year, like schnobble tip, round tip, contrasting tip, etc.
