With the crescent buttplate it will be a model 1899A, as Loggah said. The 24" barrel might be special order, because 26" was the standard - or cut down 2" as he suggested.
The new 25-35 ammo is fine for old 25-35 rifles including the Savage rifles, if the Savage rifle is good.
If the serial number (or part of it) is on the barrel, it will be on the bottom of the barrel by the OFF stamp.
