This scope is a vintage 4-power external-adjustment rifle scope produced by the Winchester Repeating Arms Company between 1909 and 1928. Part of the classic Winchester "B" series (which included the B3 and B5 models), it featured a steel tube build and was offered as an optional accessory for various period rifles. This scope is in very good condition with a nice blue finish and fire blue finish on some parts. Has Scope ring mounts. The reticle is visible and optics are clear with a slight blur and made it harder to get a clear picture.
