Savage model 20 bolt action

I was recently given a savage model 20 bolt action rifle. The ONLY thing stamped on the weapon is "Savage model 20" & serial # "119XX". I have no idea what caliber this rifle is. It has a heavy octagon barrel, rear sights that are adjustable for windage and elevation. Web searches have turned up nothing. Is this rifle rare or worth much? Any help would be great.

I've also never hear of a model 20, I would look for a savage collector site, maybe the three collectors in the US have found each other Sorry, I just don't think I've even seen a Savage group at the NRA convention in collectors row. With a heavy octagon (or hexagon) this leads me to believe it's an older rifle, any clue as to it's age or a photo?

hello,,savage made a model 1920 bolt action rifle but it was chambered for centerfire cartridges ,,is this a centerfire or a rim fire rifle ???,,that should be fairly easy to tell by looking at the bolt and where the fireing pin is located ,,not sure if they ever had octagon barrels though,, made from 1920-31
