Rick, All my rifles are marked like that! near the rear sight, its like they started with the first line and kept rolling the barrel,but leaving a wider space where the rear sight dovetail is. I checked my rear sights,2 rifles have the Lyman 6B rear sight,one has a marbles 95 folding rear ,both these sights are listed as optional for the Stevens high-power rifle. The 4th rifle has the stevens 112 rear sight,it does have an adjustable blade and does look somewhat like the early savage sight, i'll try to get cheryl to post a picture later. Don
