The Sears and Roebuck Model 10153521, commonly referred to as the .30-30, was manufactured by Marlin Firearms Company. This model was part of a partnership where Sears sold firearms made by various manufacturers under their own label. The .30-30 caliber is well-known for its use in lever-action rifles, particularly among hunters and sports shooters.
