Great pictures on the 20. It has been stamped chambers length, I assume by Savage at a later date. The Barrels are stamped Chromox Fluid which I wonder about. Has anyone pulled the production card? Is there one for this gun? The serial number on the barrels has been restamped later. The font type is different on the numbers 1,4 and 3. Are the barrels a factory Savage replacement set? Does it letter? Or is there another reason for the mismatched serial number fonts? I’d still like to buy it. If these old guns could talk the stories they have to tell us.
